HERE IS YOUR ANSWER :-

Let p be the smaller force then it is given that

p + q = 18. ------------(1)

R = √P^2 + q^2 + 2pqcos¢. = 12 ------(2)

q sin¢/p+cos. ¢ = tan¢ = tan90°
p+ qcos¢ = 0 ---------(3)

substituting the value of p

q (1- cos ¢ ) =18 ----------(4)

and subtracting square of equation (2) from (1)

2 pq [1-cos¢] = 18^2 - 12^2 = 180 -----------(5)

Dividing equation (5) by (4)

2p = 10

p= 5 , so q = 13

so the magnitude of forces are (5 and 13)

hence , correct answer is (c)
