Problem
A research apparatus delivers charged droplets to a metallic node where three narrow tubes meet. Measurements yield the following information for a particular instant:
• In tube 1, charged droplets carrying net charge q1=25μC pass the node every 5.0ms, moving toward the node.
• In tube 2, current I2=3.6A exits the node.
• In tube 3, current I3 (magnitude and direction unknown) is monitored by a sensor downstream from the node.
Assume the charge on the droplets in tube 1 is uniformly distributed in time.
(a) Compute the electric current in tube 1 expressed in amperes.
(b) Determine the magnitude and direction of the current I3 in tube 3 at that instant.
(c) If the droplet frequency in tube 1 were doubled while all other conditions remained unchanged, state quantitatively how I3 would be affected and justify your reasoning.
