Question

-95.Two charges (Q1 = 2x10^-9 C and Q2 = 4x10^-8C) are separated by 0.1m. What is the electricforce between the charges? (Remember that there is one specific equation for theelectric force between two charges, and that "k" is the coulomb constant: k = 9x10 .)**Make sure to pay attention that the charges have negative exponents.

Answer 1

Answer: Electric force between the charges = 0.000072 N

Step-by-step explanation:

We would apply the Coulomb's law which is expressed as

F = kq1q2/r^2

Where

F is the electric force between the charges

r is the distance between the center of both charges

q1 and q2 are the magnitude of the charges

k is the charge constant and k = 9 x 10^9 N/m^2C^2

From the information given,

q1 = 2 x 10^-9 C

q2 = 4 x 10^-8C

r = 0.1

By substituting these values into the formula,

F = (9 x 10^9 x 2 x 10^-9 x 4 x 10^-8)/(0.1)^2

F = 0.000072 N
