From the figure, the gravitational potential at '0' due to three point masses is

A

`(Gm)/(l)(2+(1)/(sqrt2))`

B

`(Gm)/(l)(sqrt+(1)/(2))`

C

`(3Gm)/(l)`

D

`(2Gm)/(l)`

Text Solution

Verified by Experts

The correct Answer is:
a
`v=v_(1)+v_(2)+v_(3)`
`=-(Gm)/(l)-(Gm)/(l)-(Gm)/(sqrt2l)`
`=-(Gm)/(l)[1+1+(1)/(sqrt2)]=-(Gm)/(l)[2+(1)/(sqrt2)]`.

From a solid sphere of mass M and radius R, a spherical portion of radius R/2 is removed, as shown in the figure Taking gravitational potential V =0at r = oo, the potential at (G = gravitational constatn)

Assertion : If gravitational potential at some point is zero, then gravitational field strength at that point will also be zero. Reason : Except at infinity gravitational potential due to a system of point masses at some finite distance can't be zero.

From a solid sphere of mass M and radius R, a spherical portion of radiu (R )/(2) is removed as shown in the figure. Taking gravitational potential V = 0 at r = oo , the potential at the centre of the cavity thus formed is (G = gravitational constant)

Gravitational Potential At A Point Due To The Earth

A satellite of mass 50 kg moves from a point where the gravitational potential due to the Earth is -20MNkg^(-1) to another point where the gravitational potential is -60MJkg^(-1) .During the change of position, it has moved

Three mass points each of mass m are placed at the vertices of an equilateral tringale of side l. What is the gravitational field and potential due to three masses at the centroid of the triangle ?

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 : The magnitude of the gravitational force on one body due to other two bodies is
