hey I am in class 6 why did you ask
Answer:
F=50kg
D=5m
W=FD
therefore work done is 250Nm
Answer:

Explanation:
The electric force between two charged objects is given by:

where:
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is their separation
In this problem:
q1 = 2.0 C
q2 = 1.0 C
r = 2 m
So, the electric force is
