Question

A 5 kg block has a uniform rope of mass 2 kg attached to its underside and a 3 kg block is
suspended from the other end of the rope. The whole system is accelerated upward at
2 m/s by an external force F. (g = 10 m/s2)
(A) The value of Fo is 120 N.
(B) The net force on rope is 4 N.
(C) The tension at middle point of the rope is 48 N.
(D) None of these​

Answer 1

Answer:

(B) The net force on rope is 4 N.

HOPE IT HELPS!!

Answer 2

The system is accelerated upward at the net force on rope is 4N.

Explanation:

For calculating the value of $f_{0}$ consider two blocks two blocks with the rope as a system of whole system.

$F_{0}-100=10*2$

$F=120N$

According to newton's law, net force on rope.

$F=ma$

$=2*2$

$=4N$.
