A force of 
is applied on lower block as shown in figure. The work done by lower block on upper block for a displacement of 3 m of the upper block with respect to ground is (Take, 
)
Text Solution
Verified by ExpertsThe correct answer is:
B
Maximum acceleration of 1 kg block,
Common acceleration without relative motion between
two blocks, 
Since, 
There will be no relative motion and blocks will move with acceleration 
.
Force of friction by lower block on upper block,
Work done,
