Question

There are two types of charges namely positive and negative.

1. List any two basic properties of electric charge.

2. Can a body have a charge of 0.8 × 10^-19 C? Which basic property of electric charge is the reason for your answer?

3. Name the basic property of electric charge that you can see in the equation.

Rn₈₆ → pO₈₄ + He₂

Answer 1

1. Quantization of electric charge. Conservation of electric charge.

2. No. According to quantisation of charge, total charge is Q = ne when ‘n’ is an integer. Here

n = \(\frac{0.8\times10^{-19}}{1.6\times10^{-19}}\) = 0.5 n is a fractional value.
