NEET Physics Laws of Motion Questions Solved

A block A of mass m1 rests on a horizontal table. A light string connected to it passes over a frictionless pulley at the edge of table and from its other end another block B of mass m2 is suspended. The coefficient of kinetic friction between the block and the table is  μk. When the block A is sliding on the table, the tension in the string is

(a) (m2km1)g/(m1+m2)

(b) (m2km1)g/(m1+m2)

(c) m1m2(1+μk)g/(m1+m2)

(d) m1m2(1-μk)g/(m1+m2)
