Question

Two forces of magnitude are in the ratio 3 is to 5 give the resultant of 35 newton if the angle of inclination is 60 degree calculate the magnitude of each force

Answer 1

Answer:The magnitude of the two forces will be 15N and 25N respectively.

Explanation:Let us assume that the force applied be X.

i.e 3x and 5x.

R=35N

Angle=60°

35=√a^2 +b^2 + 2abcostheta

35=√9x^2+25x^2+30x^2*1/2

35=√49x^2

35=7x

X=5

3x=3*5=15N

5x=5*5=25N
