A block `A` of mass `m_(1)` 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 `m_(2)` is suspended. The coefficient of knetic friction between the block and table is `mu_(k)` . When the block `A` is sliding on the table, the tension in the string is.

Options

A. `((m_(2)+ mu_(k)m_(1))g)/((m_(1)+m_(2)))`
B. `((m_(2) -mu_(k)m_(1))g)/((m_(1)+m_(2)))`
C. `(m_(1)m_(2) (1+mu_(k))g)/((m_(1) +m_(2)))`
D. `(m_(1)m_(2)(1-mu_(k))g)/((m_(1) +m_(2)))`

Answer

C
