Question

If one starts 10 field lines from a point charge of 2Q. then he/she will end 20 field lines on −Q.

A. True
B. False

Answer 1

The statement is False. A charge of 2Q will have twice as many field lines as a charge of Q.

Step-by-step explanation:

The statement is False. The number of field lines originating or terminating at a charge is proportional to the magnitude of that charge. A charge of 2Q will have twice as many lines as a charge of Q. Therefore, if one starts 10 field lines from a point charge of 2Q, they will end 10 field lines on -Q, not 20.
