Asource charge generates an electric field of 1236 n/c at a distance of 4 m. what is the magnitude of the source charge?

Explanation:

A region around a charged particle where another charged particle experiences a force is called electric field.

Electric field strength is defined as the force experienced by unit positive test cahrge when placed in an electric field.

The formula of electric field due to a point cahrge is given by

E = k q / r^2

Where k is a constant and it's value is

9 × 10^9 Nm^2/C^2.

1236 = 9 × 10^9 × q / 16

q = 1.48 × 10^-3 Coulomb

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
