Question

There are two vectors having magnitude 3 units and 4 units respectively,
38. What should be the resultant if angle between them in 60%"?
​

Answer 1

Explanation:

resultant is √37 or 6.08

Answer 2

I think you mean 60 degrees not 60 %

Let the vectors be A & B

Let the resultant be r

r = root(A^2+B^2+2ABcostheta)

A = 3 units

B = 4 units

r = ? units

r = root(3x3+4x4+2x3x4xcos60)

r = root(25 + 12)

r = root37

I think it's correct
