Question

If the resultant of two force each of magnitude 100 n is 100 root 3 n. the angle between the two force is

Answer 1

Answer:

Explanation:

According to the question ,

√F is the resultant force.

Let the angle be x°

As, resultant force = √( F^2 + F^2 +2 F^2 cos x )

√F = √( F^2 + F^2 +2 F^2 cos x )

or, F = F^2 + F^2 +2 F^2 cos x

or, F = 2 F^2 + 2F^2 cos x

or, F = 2F^2(1+ cos x)

or, 1 = 2F ( 1+ cos x)

or, 1/2F = 1+ cos x

or, 0.5 F = 1 + cos x

or , 0.5 F - 1 = cos x

or, x = cos ^-1 (0.5F - 1)

Answer 2
