Question

a point charge produces an electric field of magnitude 60.0 NC at a point 2.50 m away. what is the absolute value of the charge?

Answer 1

To solve this problem, apply the definition given by the magnetic field. Through it we will clear the variable corresponding to the load and find the desired value. This definition is mathematically given by the function:

`E = k(q)/(r^2)`

Here,

k = Coulomb's Constant

q = Charge

r = Distance

Replacing,

`60 = (9*10^9) (q)/(2.5^2)`

Rearrangin to find the charge

`q = (60(2.5)^2)/(9*10^9)`

`q = 4.166*10^(-8)C`

Therefore the absolute value of the charge is
`4.166*10^(-8)C`
