A) \[ma\]
B) \[\frac{5}{3}\,ma\]
C) \[\frac{3}{2}\,ma\]
D) \[2\,ma\]
Correct Answer: C
Solution :
[c] From figure, \[ma=F-f\] ?(i) Mass = m And, torque \[\tau =I\alpha \] \[\frac{m{{R}^{2}}}{2}\alpha =fR\] \[\frac{m{{R}^{2}}}{2}\frac{a}{R}=fR\] \[\left[ \therefore \alpha \frac{a}{R} \right]\] \[\frac{ma}{2}=f\] ?(ii) Put this value in equation (i), \[ma=F-\frac{ma}{2}\] or \[F-\frac{3ma}{2}\]You need to login to perform this action.
