What is the force actig on an object of mass 10kg moving with a uniform velocity of 10m/s |
| Answer» <html><body><p><strong>Answer:Here as the mass 10 kg is considered to be constant, so it depends over the nature of its <a href="https://interviewquestions.tuteehub.com/tag/instantaneous-516608" style="font-weight:bold;" target="_blank" title="Click to know more about INSTANTANEOUS">INSTANTANEOUS</a> <a href="https://interviewquestions.tuteehub.com/tag/velocity-1444512" style="font-weight:bold;" target="_blank" title="Click to know more about VELOCITY">VELOCITY</a>. If it is moving with uniform velocity 10 m/s, then the resultant force must be zero.</strong></p><p></p><p><strong>Explanation:Given,</strong></p><p><strong></strong></p><p><strong>An object of mass(m) = 10 kg and</strong></p><p><strong></strong></p><p><strong>Uniform velocity = 110\dfrac{m}{s}</strong></p><p><strong></strong></p><p><strong>To find, the force <a href="https://interviewquestions.tuteehub.com/tag/acting-269" style="font-weight:bold;" target="_blank" title="Click to know more about ACTING">ACTING</a> on an object(<a href="https://interviewquestions.tuteehub.com/tag/f-455800" style="font-weight:bold;" target="_blank" title="Click to know more about F">F</a>) = ?</strong></p><p><strong></strong></p><p><strong>We know that,</strong></p><p><strong></strong></p><p><strong>Force, F = ma</strong></p><p><strong></strong></p><p><strong>Where , m = mass of an object and</strong></p><p><strong></strong></p><p><strong>a = acceeration of an object</strong></p><p><strong></strong></p><p><strong>The velocity of <a href="https://interviewquestions.tuteehub.com/tag/body-900196" style="font-weight:bold;" target="_blank" title="Click to know more about BODY">BODY</a> is no change(uniform).</strong></p><p><strong></strong></p><p><strong>Acceleration, a = 0</strong></p><p><strong></strong></p><p><strong>∴ F = 10 × 0</strong></p><p><strong></strong></p><p><strong>= 0 N</strong></p><p><strong></strong></p><p><strong>Hence, the force acting on an object(F) = 0 N</strong></p><p><strong></strong></p><p></p></body></html> | |
