Find the magnitude of the electric field at a point midway between two charges +35.5 × 10−9 C and +77.2 × 10−9 C separated by a distance of 46.1 cm. The value of the Coulomb constant is 8.99 × 109 N · m2 /C 2 . Answer in units of N/C.

The electric field at the midway between two charges is 7059.9N/C

Explanation:

Given-

charge, q1 = 35.5 X 10⁻⁹ C

q2 = 77.2 X 10⁻⁹C

distance, r = 46.1cm

midway distance, r = 23.05 cm = 0.2305 m

Coulomb's constant, k = 8.99 X 10⁹ Nm²/C²

Electric field, E = ?

We know,

Therefore, electric field at the midway between two charges is 7059.9N/C

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

1= 26.17

2= 1.17

3=30.86

4=5.86
