Answer:Magnitude of tension in the string is less than the weight of rock

Explanation:

Given

Rock is suspended from the string and it accelerates downward

Let T be the Tension in the string

thus

mg-T=ma

where a = acceleration of rock

T=mg-ma

T=m (g-a)

Thus Tension in the string is less than the weight of rock
