Acharge q1 = 20.91 mc is placed r = 37.15 cm to the left of a charge q2 = 67.23 mc and both charges are held stationary. point a is located r3 = 0.1115 cm to the right of q. a particle with a charge of q = −6.551 μc and a mass of 42.81 g is placed at rest at a distance r2 = 32.99 cm above q2. if the particle were to be released from rest, calculating its exact path would be a challenging problem. however, it is possible to make some definite predictions about the future motion of the particle.
if the path of the particle were to pass through point a, what would be its speed va at that point?
