Question

Three forces 2N, 3N and 4N acting simultaneously on body of mass 2kg are removed then acceleration of the body will be

Answer 1

Explanation:

Their magnitudes are 3N,4N and 5 N. Then, ... Two forces of magnitudes 3N and 4N respectively are acting on a body. ... The body will certainly have an acceleration of these.

Answer 2

Explanation:

Here the 3 forces are in equilibrium such that resultant of any two forces is balanced by 3rd force.

For this question

Let us take the forces 2N And 4N which are balanced by third force 3N so the resultant of the forces 2 and 4 is 3,which is the force applied on a body of 2kg mass after the 3rd force 3N is removed

Now for acceleration we have F=ma

Or, 3=2a

a=1.5m/s sq

Hope it helps.
