Testing the Electric Field

A point charge is placed 3 m from a 4 UC charge. What is the strength of the electric field on the point charge at this
distance? (Round to the nearest whole number.)

Answer 1

The strength of the electric field on the point charge at this distance is 4000 N.

Step-by-step explanation:

The electric field strength is determined using the formula
`E=(kQ)/(d^(2) )`

Thus, field strength is directly proportional to the charge of the charge and inversely proportional to the square of the distance between them. In the above equation, Q is the charge and d is the distance, k is the constant 9×
`10^(9)`

So, the electric field strength will be

`E=(9*10^(9) *4*10^(-6) )/(9)=4*10^(3) =4000 N`

So the electric field strength is 4000 N.
