Question

Find the magnitude of two forces such that if they act at right angles

Answer 1

Answer:

Let the forces be f1 and f2

f1²+f2²=10

as the angle between them is 90 degrees

when angle is 60

f1²+f2²+2*f1*f2*cos(60)=13

10+f1*f2=13

3=f1*f2

(f1+f2)²=f1²+f2²+2*f1*f2=10+6=16

f1+f2=4...(1)

f1-f2=√((f1+f2)²-4f1*f2)=2...(2)

from (1) and (2) u get

f1= 3 N f2= 1 N
