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
$(a)$ Explain the meaning of the statement ‘electric charge of a body is quantised’.
$(b)$ Why can one ignore quantisation of electric charge when dealing with macroscopic i.e., large scale charges?
Explain the superposition principle for static electric forces and write its general equation.
Write some important points for vector form of Coulomb’s law.
Write Coulomb’s law and explain its scalar form.
Three charges $ - {q_1},\,\, + {q_2}$ and $ - {q_3}$ are placed as shown in the figure. The $x$-component of the force on $ - {q_1}$ is proportional to
