Answer:
The work done will also be twice the former value; 4J
Explanation:
Mathematically,
work = force x distance
W = F x d
Given;
W = 2J
d = 20m
F = ?
Hence
[tex]2= F*20\\F=\frac{2}{20}\\F=0.1N[/tex]
When the force F is twice, we have
F = 2 x 0.1
F = 0.2N
Since the distance remains constant, the new work done becomes
W = 0.2 x 20
W = 4J
