Question
Find the distance between centre of gravity and centre of mass of a two particle system attached to the ends of a light rod. Each particle has same mass. Length of the rod is R, where R is the radius of Earth
Options
A.R
B.R / 2
C.Zero
D.R / 4
Solution
Center of gravity of the two particles.
XCG =
= R
The centre of mass of the two particle system is at
XCM =
XCG =
= RThe centre of mass of the two particle system is at
XCM =
