An insect of mass m is pulled slowly from ground on a rough hemispherical surface upto the top of the hemisphere with a tangential force.The radius of the hemisphere is R and coefficient of friction between insect and hemisphere is 0.5 .The work done by the force is KmgR/2,then find the value of K.
