What is the amount of work done in bringing a mass from the surface of Earth on one side to a point diametrically opposite on the other side?

A

Zero

B

Positive

C

Negative

D

Nothing can be said

Text Solution

Verified by Experts

The correct Answer is:
A
As surface is smooth so work done against friction is zero. Also the displacement and force of gravity are perpendicular so work done against gravity is zero.

The work done to take a particle of mass m from surface of the earth to a height equal to 2R is

There are three identical point mass bodies each of mass m locted at the vertices of an equilateral triangle with side r . They are experting gravitational force of attraction on each other, which can be given by Newton's law of gravitaiton. Each mass body produces its gravitational field in the surrounding region. the magnitude of gravitational field at a point due to a point mass body is the measure of gravitaitonal intensity at that point. The gravitational potential at a point in a gravitational field is the amount of workdone in bringing a unit mass body infinity to the given point without acceleration. Answer the following questions : Work done in taking one body far away from the other two bodies is

Assertion : The work done in bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down along the vertical side . Reason : The gravitational force on the body along the inclined plane is the same as that along the vertical side.
