Question

The maximum value of resultant of

two forces P and Q is 31 N and minimum value of resultant is 17 N. Find the forces.​

Answer 1

Answer:

P = 24 and. Q = 7

Explanation:

Maximus value of resultant force of P and Q is when the angle between the two forces is zero

Rmax = P+Q

P+Q = 31

Minimum value of resultant force of P and Q is when the angle between the two forces is 180 degree.

Rmin = P - Q = 17

Now,

(P+Q)+(P-Q) = 31 + 17

2P = 48

P = 24

So, Q = 7.
