Question

A body of mass 5 kg is acted upon by two perpendicular forces 8 newton and 6 newton

Answer 1

two forces are perpendicular to each other.

resultant force will be,

= whole root of 8^2+ 6^2 + 2×8×6×cos 90

= whole root of 64 + 36 + 0

.....(cos 90= 0)

= root of 100

= 10 N

hence, the resultant force is 10 N.

mass of a body is 5 kg.

accleration produced= F/m

= 10/5=2 m/s^2
