Question

A block is applied two forces of magnitude 5N each. One force is acting towards East and the other

acting along 60° North of East. The resultant of the two forces (in N) is of magnitude :​

Answer 1

Answer:

let the east direction be along +x axis and the north direction ⬆️ be along the +y axis.

5 N force along ➡️

+

5cos60° N also along ➡️

=

$5 + 5 \times \frac{1 }{2}$

(cos60° =1/2)

therefore total magnitude of force acting along east =5+2.5

=7.5 N
