The electric field due to a single point charge is spherically symmetric because the field radiates equally in all directions from the charge. The field strength depends only on the distance from the charge, not the direction. Answer: (c) spherically symmetric. For more visit here: https://www.tiwarRead more

For a short electric dipole, the electric field intensity on the axial line is twice that on the equatorial line at the same distance. This follows from the standard dipole field equations: E_axial = (2kP) / r³ and E_equatorial = (kP) / r³, giving E_axial / E_equatorial = 2. Answer: (a) 2. For moreRead more

When a plastic comb is passed through dry hair, it acquires a negative charge due to the transfer of electrons from the hair to the comb. Hair loses electrons and becomes positively charged, while the comb gains electrons and becomes negatively charged, following the principle of triboelectric chargRead more
