Question

A large conducting plate is placed between 2 positive charges $Q_1$ and $Q_2$.

• A. $Q_1$ will be attracted towards plate
• B. $Q_1$ will be repelled away from plate
• C. There will be no net force on $Q_1$
• D. net force on $Q_1$ will be away from $Q_2$

Answer 1

The correct option is A $Q_1$ will be attracted towards plate

As plate is very large, effect of $Q_2$ on $Q_1$ will be zero due to electrostatic sheilding. Hence, the force on the charges will be due to the induced charges on the plate's surface which is near to them.
