Question

Two forces whose magnitudes are in the ratio of 3: 5 give resultant of 35 N. If the angle of inclination be so calculate the magnitude of each force.​

Answer 1

Answer:

15N and 25N

Explanation:

Using cosine law and assuming the forces to be of magnitudes 3x and 5x,

c= a 2 +b 2 +2abcosθ35= 34x 2+15x

therefore x=35/7=5.

Forces are thus equal to 15 N and 25 N.
