Question
If we increase the magnitude of the two charges the electric force_____________.
- Increases
- Decreases
- Remains the same
- Becomes zero
Hint:
the force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.
The correct answer is: Increases
As F = qE
Coulomb's law calculates the magnitude of the force F between two point charges, q1 and q2, separated by a distance r. F=k|q1q2|r2. k=8.988×109N⋅m2C2≈8.99×109N⋅m2C2.
Since Force is directly proportional with two charges. So with increase in magnitude of 2 charges th electric force also will increase.

The electric force ___________ on the medium between the charges.
- K= 1/4πε
- The value of k depends on the electric permittivity of the medium (ε).
- And the electric permittivity of a medium (ε) depends on the nature of the medium.
- Therefore, the value of K is different for different medium.
- Hence, the electrostatic force depends on the medium between the two charges.
