Question

Two forces 50N and 65N acts on a body simultaneously in opposite
direction but in same straight line, if mass of the 1st body is 5 kg then
acceleration in the body is
la) 23m/s2
(b) 1m/s2 (c) 3m/s2 (d) 22m/s2​

Answer 1

Answer:

3 ms–²

Explanation:

AS THEY ACT IN OPPOSITE DIRECTIONS,

NET FORCE = F1 - F2

HENCE,

NET FORCE = (65-50)N

NET FORCE = 15N

WE KNOW THAT

FORCE = MASS * ACCELERATION

HENCE ,

ACCELERATION = FORCE/MASS

SO

ACCELERATION = (15/5) ms–²

SO , ACCELERATION= 3ms–²
