A solid sphere of mass 0.50 kg is kept on a horizontal surface. The coefficient of static friction between the surfaces in contact is 2/7. What maximum force can be applied at the highest point in the horizontal direction so that the sphere does not slip on the surface?
Given:
Mass of the sphere= 0.50 kg
Coefficient of static friction= 2/7
Consider the moment about the center of the sphere
