The physics teacher gave a rod of length 'L' units to Roy and the teacher asked Roy to find the shift in the centre of gravity when `1//4` of the total length of the rod is removed. What will be the Roy's answer in terms of L?

Explanation

Original length of rod = L units
CG = `L/2` units
New length of rod = `L- L/4= (3L)/(4)`
New position of CG = `(3L)/(8)`
Shift in CG= `L/2-(3L)/(8)=(4L-3L)/(8) =L/8` units
