Question

two force one of 12n and another of 24n act on a body in a such way the make an angle of 90% with each other .find the result of the two force?

Answer 1

Force A=12N

Force B=24N

Resultant R=√(A^2+B^2+2ABcos theta)

=√(144+576+2*24*12*cos90°)

=√(144+576+576*0)

=√(720)

=26.833 N(approx.)
