A small glass bead charged to 6.5 nC is in the plane that bisects a thin, uniformly charged, 10-cm-long glass rod and is 4.0 cm from the rod's center. The bead is repelled from the rod with a force of 940 μN.

Part A

What is the total charge on the rod?

Express your answer with the appropriate units.

The total charge on the rod is 41.18 nC

Explanation:

Given;

length of glass rod, L = 10 cm = 0.1 m

radius of the rod, r = 4 cm = 0.04 m

Force of repulsion = 940 μN = 940 × 10⁻⁶ N

Charge on the bead = 6.5 nC = 6.5 × 10⁻⁹ C

Charge on the rod, Q = ?

From coulomb's law;

Where;

F is the force of repulsion in N

q₁ and q₂ are the charges on the bead and rod

R is the resultant distance between the two charges;

K is coulomb's constant = 8.99 x 10⁹ Nm²/C²

Therefore, the total charge on the rod is 41.18 nC

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
