Read More In the shown arrangement, relative acceleration of 9 kg block with respect to 5 kg block is (Assume pulleys are and strings are ideal) 2 Clear Response​

Answer 1

Answer:

In the arrangement shown in figure, pulleys are massless and frictionless and threads are inextensible, block of mass m 1

will remain at rest, if:

Answer 2

Answer:

Explanation:

No, the accelerating elevator will affect the weight of both sides of the beam balance. So, the net effect of the accelerating elevator cancels out, and we get the actual mass.

During free fall:

Acceleration of the boy = Acceleration of mass M = g

Acceleration of mass M w.r.t. boy, a = 0

So, the force exerted by the box on the boy's head = M × a = 0

Yes, the force greatly increases during the period he balances himself after striking the ground because of the weight of the box.
