Question

Given: Q1 = +10 uc = 1.0 x 10-5C
Q2 = -15 uc = -1.5 x 10-5 C
K = 9.0 x 109 Nm2/C2
r= 6.0 m
Determine F.
-0.42
-0.23
-0.038

Answer 1

Answer:

-0.038 N

Explanation:

F=K Q1 Q2/r^2 by COULOMB'S LAW

F= 9×10^9×1×10^-5×-1.5×10^-5/(6)^2

F= -0.038 N

Answer 2

Answer:

-0.038

Explanation:

$F=(K*Q_1*Q_2)/(r^2)$

insert the numbers

Q1 = 1.0*10^-5

Q2 = -1.5*10^-5

K = 9.0*10^9

r= 6.0 m

F= -0.038
