Question

A block of mass `M_(1)` is attached with a spring constant `k`. The whole arrangement is placed on a vechile as shown in the figure. If the vehicle starts moving towards right with an acceleration a (there is no friction anywhere), then :
.
A. maximum elongation in the spring is `(Ma)/(k)`
B. maximum elongation in the spring is `(2Ma)/(k)`
C. maximum compression in the spring `(2ma)/(k)`
D. maximum compression in the spring is zero.

Answer 1

Correct Answer - B::D
`Max = (1)/(2) Kx^(2) , X = (2Ma)/(K)`.
