A block of mass m is attached to an ideal spring and system lies in vertical plane as shown. Initially the supporting plane is placed so that spring remains in its natural length then the plane is moved very slowly downwards. The graph showing variation of normal reaction applied by mass on supporting plane with distance travelled by block is –
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
as supporting plane is lowered slowly
N = mg – kx
