A body of mass 
is moving on a rough horizontal plane. A block of mass 
is connected to the 
mass by a string of negligible mass through a smooth pulley as shown in the below figure. The tension in the string is 
. The coefficient of kinetic friction between the heavier mass and the surface is 
Text Solution
Verified by ExpertsThe correct answer is:
B
Given, tension in string 
Mass 
Let acceleration of the block be 
.
From the free body diagram of body of mass 
.
Coefficient of kinetic friction is 0.035 .
