Question

Two charges q1 and q2 are separated by a distance d and exert a force F on each other. What new force F ′ would exist if q1 is quadrupled? 1. None of these 2. F ′ = 1 4 F 3. F ′ = 1 16 F 4. F ′ = 16 F 5. F ′ = 0 6. F ′ = 4 F

Answer 1

Answer: F ′ = 1 4 F

Step-by-step explanation:

Answer 2

Answer:F'=4F

Step-by-step explanation:

Given

There are Two charges
`q_1` and
`q_2`

Force Between them is F

separation between them is d

Electrostatic Force is given by

`F=(kq_1q_2)/(d^2)`

If
`q_1` is quadrupled i.e.
`q_1'=4q_1`

`F'` is given by

`F'=(kq_1'q_2)/(d^2)`

`F'=(4kq_1q_2)/(d^2)`

`F'=4(kq_1q_2)/(d^2)`

`F'=4F`

Four times of original Force
