Question

- When should one use the test charge equation to solve a problem?

- To study the field
- To study an accumulation of electric charge
- To study the work to move a charge, without gaining acceleration
- To study the energy to needed to move a charge against the field

- If q
_{0}and q are infinitely far apart, their interaction would have a measurement of …

- All real values
- All values on that line integral
- Zero
- Unknown due to the unknown distance of infinite

- If given the following info, what would you know?

E_{0} = E_{F}

- It shows that the system is not enclosed
- Energy is being created
- The total Work of the system will equal zero
- Conservation law of energy is does not apply

Answer #1

1. a option is correct.

Test charge is use to find the electric field strength is referred to as a test charge since it is used to test the field strength. The test charge has a quantity of charge denoted by the symbol q.

F = kQq/r^2

2. Zero...c is correct option

We know

Electric potential=kqQ/r

Ifbr will be infinity then potential will be zero.

3. C option is correct.

Total work done of system will be zero.

Other option are

Energy never created.

Conservation of law of energy is applicable of no loss takes place.
