Given
Length of the rope = 20m
Length of the pole = 10m
Force = 100N
To Find:
The force with which the pole will be pressed downwards
Solution:
Applying the formula -
Length of the pole/ Length of the rope = F/Total force
10/20 = F/100
F = 100 × 10 / 20
F = 1000/20
F = 50
Answer: The force with which the pole will be pressed downwards will be 50N.
