In some region, the gravitational field ...

In some region, the gravitational field is zero. The gravitational potential in this region

A

must be zero

B

cannot be zero

C

must be constant

D

must be variable

Text Solution

Verified by Experts

The correct Answer is:
c
`I_(g)=-[(dv)/(dl)]_("max")`
`I_(GX)=-[(dv)/(dx)], I_(GY)=-[(dv)/(dY)], I_(GZ)=-[(dv)/(dZ)]`
Derivative of constant term is always zero.

Where is the gravitational field zero and where is the gravitational potential zero, in case of Earth?

Assertion : Two spherical shells have masses m_(1) and m_(2) . Their radii are r_(1) and r_(2) . Let r be the distance of a point from centre. Then gravitational field strength and gravitational potential both are equal to zero for O lt r lt r_(1) Reason : In the region r_(1) lt r lt r_(2) , gravitational field strength due to m_(2) is zero. But gravitational potential due to m_(2) is constant (but non-zero).
