Consider two point charges of equal magnitude and opposite sign separated by a certain distance. The neutral point due to them
Does not exist
Will be in mid way between them
Lies on the perpendicular bisector of the line joining the two
Will be closer to the negative charge
A paisa coin is made up of $\mathrm{Al - Mg}$ alloy and weighs $0.75\, g$. It has a square shape and its diagonal measures $17$ $\mathrm{mm}$. It is electrically neutral and contains equal amounts of positive and negative charges.
If two charges of $1$ coulomb each are placed $1 \,km$ apart, then the force between them will be ........... $N$
A point charge of $40$ stat coulomb is placed $2$ $cm$ in front of an earthed metallic plane plate of large size. Then the force of attraction on the point charge is.....$dynes$
Force between $A$ and $B$ is $F$. If $75\%$ charge of $A$ is transferred to $B$ then force between $A$ and $B$ is
The law, governing the force between electric charges is known as
