A sphere is rolling without slipping on a fixed horizontal plane surface. In the figure, A is the point of contact. B is the centre of the sphere and C is its topmost point. Then,

Options

  1. Av _C- v _A=2 ( v _B- v _C )
  2. Bv _C- v _B= v _B- v _A
  3. C| v _C- v _A |=2 | v _B- v _C |
  4. D| v _C- v _A |=4 | v _B |

Correct answer

B. v _C- v _B= v _B- v _A

Step-by-step solution

v_A=0, v_B=v and v_C=2 v
