The block again comes to rest when the spring is elongated
by a distance 'b'. During this process. Choose the
INCORRECT option.
k(a? +b)
(a) work done by the spring on the block =
2.
(b) work done by the spring on the block =
k(a? -b)
k(a - b)
(c) co-efficient of friction =
2mg
(d) The magnitude of 'b' must be less than the magnitude of 'a'​
