Options
- Aarray lllll 3 & 4 & 1 & 2 array
- Barray lllll 2 & 4 & 1 & 3 array
- Carray lllll 1 & 2 & 3 & 4 array
- Darray lllll 4 & 1 & 2 & 3 array
Correct answer
A. array lllll 3 & 4 & 1 & 2 array
Step-by-step solution
(P) V _ cm =(R-r) rotational E= 1 4 m(R-r)^2 ^2 (Q) total kinetic energy = 1 2 m v_ cm ^2+ 1 2 I _ cm ^2= 3 4 m(R-r)^2 ^2(R) a _ c m =(R-r) i +(R-r) ^2 j
