A body of mass 5 kg is acted upon by two perpendicular forces 8 N and 6 N. Give the magnitude and direction of the acceleration of the body.

Text Solution

Verified by Experts

Resultant force = 10 N at an angle of `tan^(-1) (3//4) = 37^@` with the direction of 8 N force. Acceleration =` 2 m s^(-2)` in the direction of the resultant force.
