An arrow sign is made by cutting and rejoining a quarter part of a square plate of side 'L' as shown. The distance OC, where C is the centre of mass of the arrow, is

A

`(L)/(3)`

B

`(L)/(4)`

C

`(3L)/(8)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

`bar(x) = ((M xx 0) + ( -(M)/(4) xx (-L)/(3)) + ((M)/(4) xx (4L)/(6)))/(M) = (L)/(4)`

A star like the sun has several bodies moving around it at different distances. Consider that all of them are moving in circular orbits. Letr be the distance of the body from the centre of the star and let its linear velocity be v, angular velocity , omega kinetic energy K, gravitational potential energy U, total energy E and angular momentum I. As the radius r of the orbit increases, determine which of the above quantities increase and which ones decrease. As shown in figure, where a body of mass m is revolving around a star of mass M. Linear velocity of the body,
