Laws Of Motion Question 55
Question: A block P of mass m is placed on a frictionless horizontal surface. Another block Q of same mass is kept on P and connected to the wall with the help of a spring of spring constant k.
Options:
A)
B)
C) Zero
D)
Show Answer
Answer:
Correct Answer: B
Solution:
When two blocks performs simple harmonic motion together then at the extreme position ( at amplitude =A) Restoring force
therefore
There will be no relative motion between P and Q if pseudo force on block P is less than or just equal to limiting friction between P and Q. i.e.
