Question -

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



Answer -

2 m/s2, at an angle of 37° with aforce of 8 N

Mass of the body, m = 5 kg

Thegiven situation can be represented as follows:

Theresultant of two forces is given as:

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

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

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