Question: A bucket tied to a string is lowered at a constant acceleration of g/4 . If the mass of the bucket is 𝑚 and is lowered by a distance 𝑑, the work done by the string will be

(A) $\dfrac{mgd}{4}$

(B) $-\dfrac{3}{4}mgd$

(D) $\dfrac{4}{3}mgd$

Answer: Option (B)

Solution:

A bucket tied to a string is lowered at a constant acceleration of g/4 . If the mass of the bucket is 𝑚 and is lowered by a distance 𝑑, the work done by the string will be
