B; to produce a hypothesis.
Answer:
if one bulb burns out the other will also turn off because they are connected to each other.
Explanation:
The given data is as follows.
Electric field (E) = 
Charge (e) =
C
Formula to calculate the magnitude of force is as follows.
F = qE
= 
= 
Therefore, we can conclude that magnitude of the force on a calcium ion with charge +e is
.
