Questions
A solid sphere of mass m is lying at rest on a rough horizontal surface. The coefficient of friction between the ground and sphere is . The maximum value of F, so that the sphere will not slip, is equal to
detailed solution
Correct option is D
As sphere is rolling we can apply torque equation about point of contact (about P).FR=IPα⇒ FR=75MR2α⇒ Rα=5F7M=aEquation of translatory motionF−f=Ma⇒f=27F ………(i)For no sliding, f≤μmg ⇒ F=72μmgTalk to our academic expert!
