Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Two stationary balloons are shown at the right.
The balloons have unequal charges (Q > q) and
unequal masses (M > m). In which string is
the tension greatest?

Expert Solution

Step 1

Analyze the following diagram.

As per Newton’s third law,

Here, F_q and F_Q represent the force on the balloon A and B, respectively.

The force’s magnitude can be represented as,

Here, k and r represent the Coulomb’s law constant and the balloon’s separation, respectively.
