Question

The strength of an electric field depends on the question 12 options:

a.amount of charge that produced the field.
b.distance from the charge.
c.amount of charge on a test charge placed in the field.
d.both a and b

Answer 1

The correct option is d.both a and b.

In fact, the strength of the electric field generated by a single-point charge is given by

`E=k (q)/(r^2)`
where
k is the Coulomb's constant
q is the amount of charge that produces the field
r is the distance from the charge

We see from this formula that the strength of the electric field, E, depends only on the amount of charge that produces the field (q) and the distance from the charge (r), therefore options A and B are both correct.
