Two thin hollow plastic spheres, about the size of a ping-pong ballwith masses (m1=m2 = 2e-3 kg) have been rubbed with wool. Sphere 1has a charge q1 = -3e-9 C and is at location < 20e-2, -20e-2, 0> m. Sphere 2 has a charge q2 = -3e-9 C and is at location <-30e-2, 20e-2, 0> m. It will be useful to draw a diagram of thesituation, including the relevant vectors.
What is the relative position vector pointing from q1 to q2?
= < , , > m
What is the distance between q1 and q2?
|| = m
What is the unit vector in the direction of ?
= < , , >
What is the magnitude of the gravitational force exerted on q2 byq1?
|grav on q2| = N
What is the gravitational force (vector) exerted on q2 by q1?
grav on q2 = < , , > N
What is the electric force (vector) exerted on q2 by q1?
electric on q2 = < , , > N
