Question

A conductor carrying current cannot produce electrostatic force because:

विकल्प

• The net positive or negative charge on the conductor is zero.

• The number of electrons entering the conductor is equal to number of electrons leaving the conductor and hence, in a way conductor is electrically neutral.

• Both

  • The net positive or negative charge on the conductor is zero.
  • The number of electrons entering the conductor is equal to number of electrons leaving the conductor and hence, in a way conductor is electrically neutral.

• None of these

Answer 1

Both

• The net positive or negative charge on the conductor is zero.
• The number of electrons entering the conductor is equal to number of electrons leaving the conductor and hence, in a way conductor is electrically neutral.

Explanation:

A current-carrying conductor remains electrically neutral because the number of electrons entering it equals the number leaving it. Hence its net charge is zero, so it cannot produce an electrostatic force.
