Two blocks A and B of masses 5 kg and 2 ...

Two blocks A and B of masses `5 kg` and `2 kg` respectively connected by a spring of force constant ` = 100Nm^(-1)` are placed on an inclined plane of inclined `30^(@)` as shown in figure If the system is released from rest

A

There will be no compression or elongation in the spring if all surface are smooth

B

There will be no compression or elongation in the spring if A is rough and B is smooth

C

Maximum elongation in the spring `35 cm` If alll surface are smooth

D

There will be no compression or elongation in the spring if A is smooth and B is rough

Text Solution

Verified by Experts

The correct Answer is:
a,d
If initialy acceleration of A is greater than thet of R then there will be extension and if of B is greater than A then there will be compression in the spring otherwise the length the tength of spring will remain same
