Text Solution

Verified by Experts

The correct Answer is:
D

`a_(cm) + R alpha = 0 rArr a_(cm) + R (tau)/(I) = 0`
`((F + f))/(m) + R ((Rf - rF)/(I)) = 0`
`IF + If + mR^(2) f - mrRF = 0`
`f(I + mR^(2)) = (mrR - I) F`
`f = ((mrR -I)/(mR^(2) + I)) F`
(i) If `I gt mrR, f (-)`
(ii) If `I lt mrR, f(+)`.
