Question

11. Two forces 10 N and 35 N are acting at an
angle of 60 degree between them. Find the
magnitude of resultant force.
A) 41 N
B) 56 N
C) 23 N
D) 98 N​

Answer 1

Answer:Since typing all those formulas were getting cumbersome I just solved it on a piece of paper and uploaded it.

For reference,

I have taken vector A=10N, vector B=8N, the angle between vectors A & B as

θ (theta) = 60 degrees.

The resultant vector is C and at an angle ø (phi) with vector A.

Explanation:

Notice another thing. I have taken ø between vector A and C. If I need to know the angle between vector B and C, say angle α (alpha)

or just α = 60 degrees - θ

Hope that helps.
