Text Solution
Verified by ExpertsThe correct answer is:
A
For the given combination, if the block is displaced towards right, elongation in one spring will be equal to the compression in other and the direction offeree due to both spring will be the same and restoring in nature. Hence, both springs are effectively in parallel combination.
Therefore,
K eff = K 1 + K 2 and
