Question

two forces of magnitude 10 Newton and 20 Newton act on a body in directions making angle 30 degree and 60 degreex axis respectively. find the resultant force?​

Answer 1

Answer:

The resultant force is 29 N.

EXPLANATION:

The resultant of two forces are determined by the parallelogram rule as follows:

As the forces acting at different angle, so the resultant force will have magnitude related to the difference in the angle in which the incident forces were acted.

Here F1 and F2 are the two forces acting and their respective angles are given as   and  

So the resultant force will be

Thus, the resultant force is 29 N.

Answer 2

Explanation:

resultant force= (a^2+b^2+2*a*b*(cos(high degree -lower degree)))
