Edexcel A-Level Physics Fields and their consequences overview quiz quiz

The product of the charges and inversely proportional to the square of the distance

The sum of the two charges and directly proportional to the separation between them

The square of the distance and inversely proportional to the product of the two charges

The product of the charges and directly proportional to the distance between them

$E = Vd$

$E = \frac{V}{d}$

$E = \frac{d}{V}$

$E = V^2 d$

$CV$ measured in joules

$CV^2$ measured in joules

$F = Bqv$

$F = \frac{Bq}{v}$

$F = \frac{Bv}{q}$

$F = Bq + v$

The magnetic flux density passing straight through the coil

The rate of change of flux linkage

The total flux linkage threading the coil at that instant

The number of turns of wire making up the coil

Increases the change that caused it

Always flows clockwise

Opposes the change that caused it

Has no fixed direction

The upward normal contact force

The upthrust from the atmosphere

The drag force resisting motion

The centripetal force

Because gravity is attractive and potential is zero at infinity

Because mass can take negative values when it is placed inside a gravitational field

Because the gravitational field around a point mass is perfectly uniform everywhere

Because the distance from the mass is treated as a negative quantity in the formula

Both can repel

Both are inverse-square fields

Both have negative potential only

Both act only on charges
