Answer:
Given:
Work done = 20J, displacement = 2m
To find:
Force applied
Concept:
Work done is referred to the energy spent to move a body by a displacement of "D" by applying a force of "F".
Formulas used:
let work done be denoted by W, displacement by D, force by F.
Calculation:
W = F × D
=> 20 = F × 2
=> F = 20/2
=> F = 10 N.
So the answer is 10 N.

Answer:
- By Displacement "D" by applying a force "F" Work of the energy spend to move body .
- By using formula ;
Suppose work done be donated by W .
Force by F & displacement by D .
- By Calculation:
W = F × D .( Force × Displacement).
20 = F × 2 .
F = 20 /2 .
F = 10N.
Answer = 10N.
