A smooth table is placed horizontally and an ideal spring of spring constant 
and unexpended length of 
has one end fixed to its centre. The other end is attached to a mass of 
which is moving in a circle with constant speed 
. Then the tension in the spring and the extension of this spring beyond its normal length are
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
(given)
Restoring force = kx 
⇒ ⇒ 
⇒ ⇒ 
and Tension in the spring = kx
