A block 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 μ. When the block A is sliding on the table, the tension in the string is
Options
(a) (m2 – μ m1) g / (m1 + m2)
(b) m1m2(1+μ)g / (m1+m2)
(c) m1m2(1-μ)g / (m1+m2)
