Which statement is true of the electric field at a distance from the source charge?

a. it is independent of the source charge

b. it is directly proportional to the source charge

c. it is inversely proportional to the source charge

d. it is directly proportional to the distance

The correct answer is "It is directly proportional to the source charge".

Explanation:

The expression of the electric field at a distance from the source charge is as follows;

Here, d is the distance from the source, k is the constant and q is the charge on the source.

The electric field is directly proportional to the source charge. It is inversely proportional to the square of the distance.

The electric field increases with the decrease in the distance from the source charge. The electric field decreases with the increase in the distance from the source charge.

Therefore, the correct option is (B).

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
