Question

Consider the electric force between a pair of charged particles a certain distance apart. By Coulomb's Law: If instead, the charge of both particles is doubled, the force is _____.

a. unchanged
b. halved
c. doubled
d. quadrupled

Answer 1

Answer: C. Doubled.

Explanation: According to Coulomb's Law, the electric force between a pair of charged particles is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Therefore, if the charge on one of the particles is doubled, the force between them will be doubled.

Answer 2

the answer is d

Step-by-step explanation:

from F=Q1Q2

r².

then wen both charges are doubled

F=2Q1 ×2Q2

r²

F=4Q1Q2

r²

then 4 has to be the factor multiplied by the other part of the equation for it to balance

4F=4Q1Q2

r²

so theoretically the 4 on the LHS can cancel the 4 on the RHS
