Question

at what angle do the force p+q and p-q act so that the resultant is underroot 3psquare+q square

Answer 1

Sorry dude

I don't know answer

I really sorry

Answer 2

Answer : 60°

Explanation:

The resultant of two vectors can be governed as:

F= √(F1²+F2²+2(F1)(F2)cos(angle between the applied forces))

Now here the applied forces are p+q = F1, say and p-q= F2, say, and resultant say F = 3p²+q², so the angle can be computed by putting the values in the formula.
