Intensity of gravitational field of earth is maximum at |
| Answer» <html><body><p> Poles</p><br/><br/><p>A perfect <a href="https://interviewquestions.tuteehub.com/tag/sphere-1222094" style="font-weight:bold;" target="_blank" title="Click to know more about SPHERE">SPHERE</a> of spherically uniform density (density <a href="https://interviewquestions.tuteehub.com/tag/varies-1443299" style="font-weight:bold;" target="_blank" title="Click to know more about VARIES">VARIES</a> solely with distance from centre) would produce a gravitational field of uniform magnitude at all points on its surface, always pointing directly towards the sphere’s centre. However, the Earth deviates slightly from this ideal, and there are consequently slight deviations in both the magnitude and direction of gravity across its surface. Furthermore, the net force exerted on an object due to the Earth, called “effective gravity” or “apparent gravity”, varies due to the presence of other factors, such as inertial response to the Earth’s rotation. A scale or plumb <a href="https://interviewquestions.tuteehub.com/tag/bob-399946" style="font-weight:bold;" target="_blank" title="Click to know more about BOB">BOB</a> measures only this effective gravity. The major reason for the difference in gravity at different latitudes is that the Earth’s equatorial bulge (itself also <a href="https://interviewquestions.tuteehub.com/tag/caused-7279664" style="font-weight:bold;" target="_blank" title="Click to know more about CAUSED">CAUSED</a> by inertia) causes objects at the Equator to be farther from the planet’s centre than objects at the poles. Because the force due to gravitational attraction between two bodies (the Earth and the object being weighed) varies inversely with the <a href="https://interviewquestions.tuteehub.com/tag/square-650836" style="font-weight:bold;" target="_blank" title="Click to know more about SQUARE">SQUARE</a> of the distance between them, an object at the Equator experiences a weaker gravitational pull than an object at the poles.</p></body></html> | |

The mass of a star is two times the mass of the Sun. How it will come to an end ? |
| Answer» <html><body><p> Neutron Star</p><br/><br/><p>The mass of a star which is two times the mass of the sun turns into a neutron star. A neutron star is a type of stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Such stars are composed <a href="https://interviewquestions.tuteehub.com/tag/almost-373246" style="font-weight:bold;" target="_blank" title="Click to know more about ALMOST">ALMOST</a> entirely of neutrons, which are subatomic particles without electrical charge and with <a href="https://interviewquestions.tuteehub.com/tag/slightly-3037487" style="font-weight:bold;" target="_blank" title="Click to know more about SLIGHTLY">SLIGHTLY</a> larger mass than protons. Neutron stars are very hot and are supported against further collapse by quantum degeneracy pressure due to the Pauli’s <a href="https://interviewquestions.tuteehub.com/tag/exclusion-979009" style="font-weight:bold;" target="_blank" title="Click to know more about EXCLUSION">EXCLUSION</a> principle. This principle states that no two neutrons (or any other fermionic particles) can occupy the same place and quantum state simultaneously. A typical neutron star has a mass between about 1.4 and 3.2 solar masses ( Chandrasekhar Limit), with a corresponding radius of about 12 km if the Akmal– Pandharipande–Ravenhall equation of state (<a href="https://interviewquestions.tuteehub.com/tag/apr-380797" style="font-weight:bold;" target="_blank" title="Click to know more about APR">APR</a> EOS) is <a href="https://interviewquestions.tuteehub.com/tag/used-2318798" style="font-weight:bold;" target="_blank" title="Click to know more about USED">USED</a>.</p></body></html> | |
