Question

If I take two charges Q1 & Q2 and seperate them by distance d. If the magnitudeIf the magnitude of each charge is doubled in the separation distance between the charges is doubled what happens to the electrical force between them

Increases by a factor of 8

increases by a factor of 16

it is double is quadrupled

it stays the same

If you were a parallel plate capacitor manufacturer for pacemakers state three ways you could make larger capacitors or more capacitance

A Increase play area decrease separation between plates and decrease dielectric constant

B decrease play area increased separation between plates and decrease dielectric constant

C increase play area decrease separation between plates and increase dielectric constant

D decrease play area decrease between plates and increase dielectric constant

Answer 1

1. It stays the same.

Explanation -

2. Ans. C.

increase plates area, decrease separation between plates and increase dielectric constant.

The capacitance of a capacitor is affected by the area of the plates, the distance between the plates, and the ability of the dielectric to support electrostatic forces.

A = Area

d = Separation

e = dielectric constant.
