Here is my method:
Balance torque about the point of contact
mgrsin\alpha =F(r+rsin\alpha )
From this we can get the answer
DONT V NEED VALLUE OF μ TO SOLVE THIS UN??
*pl. bear wid poor picture quality
Here is my method:
Balance torque about the point of contact
mgrsin\alpha =F(r+rsin\alpha )
From this we can get the answer
equating the forces in the vertical and horizontal direction we can get the answer
if still not clear i will post the solution 4 it [1]
