Laws Of Motion Question 396
Question: A block of mass m is attached with massless spring of force constant k. The block is placed over a fixed rough inclined surface for which the coefficient of friction is
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: A
Solution:
As long as the block of mass m remains stationary, the block of mass M released from rest comes down by
Thus the maximum extension in the spring is
For block of mass m to just move up the incline
