A solid sphere of mass 10 kg is placed on a rough surface having coefficient of friction, 
. A constant force 
is applied along a line passing through the centre of the sphere as shown in figure. The frictional force acting on the sphere will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Let 
be the frictional force towards left for pure rolling.
Now, linear acceleration, 
… (i)
Angular acceleration, 
Also, 
… (ii)
Equating Eqs. (i) and (ii), we get
