Question

12. Two electrically-charges spheres are suspended from insulated threads a certain distance from each other. There is a certain amount of electrostatic force between them. Describe specifically (not just increase or decrease) what happens to this force in each of the scenarios below
a. The charge on one sphere is reduced by half
b. The charge on both spheres is doubled
c. The distance between the spheres is increased by a factor of three
d. The distance between the sphere is decreased to one-fourth
e. The charge of each sphere is doubled and the distance between them is doubled

Answer 1

U know the formula is
F=k(q1*q2/r^2)

Answer 2

Here k is a constant

Answer 3

Force F is directly proportional to q1*q2

Answer 4

F is inversely proportional to r^2

Answer 5

So r increases F decreses

Answer 6

And r decreases F increases

Answer 7

If q1*q2 increses then F increases

Answer 8

If q1*q2 decreses then F decreses

Answer 9

R u getting it?

Answer 10

Response plz!!!
