Complete question is;
Objects 1 and 2 attract each other with a electrostatic force of 36.0 units. If the charge of Object 2 is doubled, then the new electrostatic force will be _____ units.
Answer:
72 N
Step-by-step explanation:
Formula for the force of attraction will be;
F = kq1•q2/r²
Where;
K is a constant
q2' = 2q2
Thus;
F' = 2kq1•q2/r²
From earlier, we saw that F = kq1•q2/r²
Thus;
F' = 2F
We are given F = 36 N. Thus; F' = 2 × 36 = 72 N
