Question

Two like parallel forces 38 N and 86 N are acting at a distance of 12 cm. What is the position of the resultant *

Answer 1

Step-by-step explanation:

Consider the point at which resultant of the forces will act, is 'x' m from the point A.

Thus the point is (1.5 - x) m far from the point B.

Thus, using the formula Torque = Distance x Force acting

20x=30(1.5−x)

or,2x=4.5−3x

or,5x=4.5

or, x=0.9mor90cm

Thus the resultant point will be 0.9 m or 90 cm far from point A
