A) \[ma\]
B) \[2 ma\]
C) \[\frac{5}{3}\]
D) \[\frac{3}{2}ma\]
Correct Answer: D
Solution :
\[F=f=ma\]and \[fR=I\alpha \]for Rolling \[a=\alpha R\] \[F-f=ma\] ??.(i) \[fR=\frac{m{{R}^{2}}}{2}.\frac{a}{R}\] \[f=\frac{ma}{2}\] ?(ii) So, \[f-\frac{ma}{2}=ma\] \[f=\frac{3}{2}ma\]You need to login to perform this action.
