Question

How is the linear charge density of a uniformly charged ring related to total amount of charge The linear charge density is the ratio of the total charge to the diameter. The linear charge density is the ratio of the diameter to the total charge. The linear charge density is the ratio of the total charge to the circumference. The linear charge density is the product of the total charge and the diameter.

Answer 1

Answer:

The linear charge density is the ratio of the total charge to the circumference.

Explanation:

As we know that linear charge density is defined at the charge per unit length in a given system of charge

here we have to find the linear charge density of the ring

so we can say it is given as

$\lambda = \frac{charge}{Length}$

now we know that length of the ring is total length of its circumference

so we can say

$\lambda = \frac{q}{L}$

$\lambda = \frac{q}{2\pi R}$

so here correct answer will be

The linear charge density is the ratio of the total charge to the circumference.
