(1979)
Show Answer
Answer:
Correct Answer: 24. (a)
(b)
Solution:
- Maximum force of friction between
Maximum force of friction between
Both the blocks will be moving downwards with same acceleration
Equation of motion of
Equation of motion of
Solving Eqs. (i) and (ii), we get
(a) Force required to move the block down the plane with constant velocity.
Since
(b) Force required to move the block up the plane with constant velocity.
