Electric field lines contract lengthwise because they represent the force experienced by a positive test charge in the field. This contraction indicates the attraction between opposite charges, as field lines always originate from positive charges and terminate at negative charges, ...

When a neutral balloon is charged, its size increases. This happens because like charges repel, causing the charged particles on the balloon’s surface to push apart. This increases the internal electrostatic pressure, slightly expanding the balloon. Thus, the correct answer ...

According to Gauss’s Law, the total electric flux (Φ) through a closed surface is given by: Φ = Qenclosed/ε0 ​where Qₑ is the total charge enclosed within the surface. The total charge enclosed is: Q enclosed = (+8Q) + (-3Q) ...

The electric field due to an electric dipole is not spherically symmetric because it depends on both the distance from the dipole and the angle with respect to the dipole axis. Instead, it has a distinct pattern with stronger fields ...

The cause of the quantization of electric charge is the transfer of an integral number of electrons. Charge is always transferred in discrete units of the elementary charge (e), where e = 1.6 × 10⁻¹⁹ C. Since electrons are the ...
