A body of weight 64 N is pushed with just enough force to start it moving across a horizontal floor and the same force continues to act afterwards. If the coefficients of static and dynamic friction are 0.6 and 0.4 respectively, the acceleration of the body will be (Acceleration due to gravity = g)
A
B
0.64 g
C
D
0.2 g
Text Solution
Verified by ExpertsThe correct answer is:
D
Weight of the body = 64N
so mass of the body 
, 
, 
Net acceleration =
