Two blocks of mass M(1) = 20 kg and M(2...

Two blocks of mass `M_(1) = 20` kg and `M_(2) = 12` kg are connected by a metal rod of mass 8 kg, the system is pulled vertically up by applying a force of 480 N as shown. The tension at the mid-point of the rod is :

A

(a)144 N

B

(b)96 N

C

(c)240 N

D

(d)192 N

Text Solution

Verified by Experts

The correct Answer is:
D
(i) `a = (480 - 400)/(40) = 2m//s^(2)`

If is the tension at mid point.
T - 160 = 16a `implies` T = 160 + 16 (2) = 192 N
