1.	Define gravitational field strength. Which plane in the solar system has the greatest gravitational field strength? What is the gravitational field strength of a planet where a 60 kg astronaut weighs 300 N?
Answer» The gravitational field strength at a point in a field is defined as the force experienced by a body of unit mass placed at that point. I = \(\frac {GM}{R^2}\) ⇒ I = g The value of I is maximum for Saturn. I = \(\frac {300N}{60kg}\) I = 5 ms^-2.

Answer»

The gravitational field strength at a point in a field is defined as the force experienced by a body of unit mass placed at that point.

I = \(\frac {GM}{R^2}\) ⇒ I = g

The value of I is maximum for Saturn.

I = \(\frac {300N}{60kg}\)

I = 5 ms^-2.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
