A body is mass 20 kg is moving on a rough horizontal plane. A block of mass 3 kg is connected to the 20 kg mass by a string of negligible mass through a smooth pulley as shown in the below figure. The tension in the string is 27 N. The coefficient of kinetic friction between the heavier mass and the surface is `(g = 10 m //s^(2))`

A

`m_1 = (m_2 cot theta)/(1- cot theta)`

B

`m_1 = (m_2 tan theta)/(1- tan theta)`

C

`T = (m_2g)/(tan theta)`

D

`T = (m_2g)/(cot theta)`
