What are positive and negative charges ? Which type of charge does electron have ?
The charges were named as positive and negative by the American scientist Benjamin Franklin.
When we add a positive number to a negative number of the same magnitude the sum is zero. This might have been the philosophy in naming the charges as positive and negative.
By this logic, charge of electron is considered as negative.
What are called electrically charged and electrically neutral bodies ?
Can you neglect the quantization of charge ?
A conductor has $14.4 \times {10^{ - 19}}coulombs$ positive charge. The conductor has(Charge on electron $ = 1.6 \times {10^{ - 19}}coulombs$)
Which is the instrument to detect the charge on the body ? Explain it with diagram.
Why the metal rods can’t be charged by holding them in hands ?
