The balancing force about the point must have a mass of 32 kg.
The principle of moments states that the sum of the anticlockwise moment about a point is equal to the sum of the clockwise moments about that point.
Moments of a force are equal to the product of the force and the perpendicular line of action of the force from that point.
Solving for the balancing force about the point:
Let the balancing force be F
Clockwise moment = F * 0.5 m
Clockwise moment = 0.5F
Anticlockwise moment = 80 * 0.2 m
Anticlockwise moment = 16 N
Equating clockwise and anticlockwise moments
0.5F = 16 N
F = 16 N / 0.5
F = 32 kg
