Question
The electric potential 1m from a certain charged particle is 4 times the potential at 1m from a second particle. How do the particles’ charges compare?
A. The first particle has 2 times the charge of the second particle.
B. The first particle has 12 the charge of the second particle.
C. The first particle has 14 the charge of the second particle.
D. The first particle has 4 times the charge of the second particle.
A. The first particle has 2 times the charge of the second particle.
B. The first particle has 12 the charge of the second particle.
C. The first particle has 14 the charge of the second particle.
D. The first particle has 4 times the charge of the second particle.
Explanation / Answer
v = kq/r
v1 = 4v2
kq1/r = 4kq2/r
q1 = 4q2
D. The first particle has 4 times the charge of the second particle
