Question

two forces each of magnitude 10n and 20n making angle 30° and 60° respectively. The magnitude of x component of their resultant will be?
​

Answer 1

Answer

5√3+10

Explanation:

let s assume that the two forces males 30 degree and 60 degree with horizontal then there components in the direction of horizontal is the direction of x axis

⇒10cos30 = 10(√3/2)=5√3

20cos60 = 20(1/2)=10

there fore the resultant in the direction of ax axis = [5√3+10]i^
