Question 40

A body of mass 4 kg resting on a smooth horizontal plane is simultaneously acted upon by two perpendicular forces 6N and 8N. Calculate the acceleration of the motion

A

2.5 ms^-1

B

3.0 ms^-1

C

4.0 ms^-1

D

4.5 ms^-1

Explanation

Share Answer Smooth plane has negligible friction
only the resultant of the perpendicular forces is acting on the body, which is given as
F =
8² + 6²

=
64 + 36

=
100

= 10N
But F = Ma
a = ^F/_M = ¹⁰/₄ = 2.5 ms^-1

Correct option: A
