Question

a body of mass 5 kilogram is acted upon by two perpendicular forces of 8 Newton and 6 Newton give the magnitude and direction of the acceleration of the body

Answer 1

Given
f1= 8 n
f2= 6 n

angle between both force is 90°


hence magnitude of resultant forces
=√(f1²+ f2²+ 2f1 *f2 cos90°)

= √(8²+6²+0)

= 10 Newton

direction of resultant force thita . = tan(-¹)(6/8)...

Mass of the body, m = 5 kg

The given situation can be represent as shown in attachment (please see attached file)

The resultant of two forces is given as:

R = √{(8)^2 + (-6)^2}=  √(64+36) = 10 N

θ is the angle made by R with the force of 8 N

Θ = tan^-1(-6/8) = -36.87°

The negative sign indicates that θ is in the clockwise direction with respect to the force of magnitude 8 N.

As per Newton’s second law of motion, the acceleration (a) of the body is given as:

F = ma

=> a= F/m = 10/5 = 2 m/s^2

I hope, this will help you
