Answer:
0.75 A
Explanation:
An electric current is a flow of charged particles.
A current is defined through its intensity, which is given by:
where
I is the current intensity
q is the charge passing through a given point in the circuit
t is the time it takes for the charge q to pass that point in the circuit
In this problem, we have:
q = 45 C is the charge passing through the point in the circuit
is the time elapsed
Therefore, the current intensity is:
Answer:
Fnet = 12 N
Explanation:
Force on a point charge due to another point charge = kq1q2 / d^2
Force on +32uC = due to + 20uC + due to -60uC
where uC = 1 x 10^-6 C and k = 9 x 10^9 N m^2 / C^2
Net Force =
Fnet = 12 N
