A rolling body is rolling without slipping on a moving plank. Relation of v and `v_1` is ……..A……….
Here, A refers to

Options

A. `v _(1) + v = R omega `
B. `v _(1) + v =- R omega `
C. `v _(1) - v = R omega `
D. None of these

Explanation

For pure rolling of sphere relative motion of point of contact of sphere and plank should be zero. For this the point of contact has a velocty equal to the velocity of planek.
