Question

Two forces whose magnitudes are in the
ratio of 3:5 and gives a resultant of
35N . If the angle of inclination be 60.
Calculate the magnitude of each force.​

Answer 1

Answer:

Let us suppose the first force to be 3x and the other force to be 5x.

Now resultant can be given by sqrt [a*a + b*b + 2abcos(angle between a and b)]

So here that is, sqrt [9x*x + 25x*x + 15x*x] = 35 N

So, 7x = 35

Or, x = 5

Thus, the values of the forces are 15N and 25N.
