Question

The electric potential 5.54 m from

a charge is -3680 V. What is the
value of the charge?
Include the sign, + or - .
(The answer is *10^-6 C. Just fill in
the number, not the power.)

Answer 1

q = - 2.26 x 10⁻⁶ C

According to answering format:

q = - 2.26

Step-by-step explanation:

The potential at a distance r from a charge q is given as follows:

`V = (kq)/(r)`

where,

V = Potential = -3680 V

k = Colomb's Constant = 9 x 10⁹ Nm²/C²

r = distance = 5.54 m

Therefore,

`-3680\ V = ((9\ x\ 10^9\ Nm^2/C^2)q)/(5.54\ m)\\\\q = ((-3680\ V)(5.54\ m))/(9\ x\ 10^9\ Nm^2/C^2)`

q = - 2.26 x 10⁻⁶ C
