The correct answer is (a) spheres. At a large distance, a collection of charges with a nonzero total sum behaves like a point charge. The equipotential surfaces around a point charge are spherical, centered on the charge. This follows from the equation V= 1/4πϵ Q/r, which depends only on distance r.Read more

The correct answer is (c) Both force and torque. In a non-uniform electric field, an electric dipole experiences torque that aligns it with the field and force due to the field gradient. The force arises because the field strength differs at each dipole charge, causing a net translational motion. ToRead more
The correct answer is (c) Both force and torque.
In a non-uniform electric field, an electric dipole experiences torque that aligns it with the field and force due to the field gradient. The force arises because the field strength differs at each dipole charge, causing a net translational motion. Torque tends to rotate the dipole, aligning it with the field direction.
The correct answer is (c) neutral or positively charged. Since X is negatively charged and repelled by Y, object Y must also be negatively charged. Object Z is attracted to Y, meaning Z could be either positively charged (opposite charges attract) or neutral (since a charged object can attract a neuRead more
The correct answer is (c) neutral or positively charged.
Since X is negatively charged and repelled by Y, object Y must also be negatively charged. Object Z is attracted to Y, meaning Z could be either positively charged (opposite charges attract) or neutral (since a charged object can attract a neutral object due to polarization).
The correct answer is (a) no net charge is enclosed by the surface. According to Gauss's law, the net electric flux through a closed surface is given by Φ = Qenc/ϵ0 . If the flux is zero, the net charge enclosed (Qenc) must also be zero, meaning either no charge is inside or equal positive and negaRead more
The correct answer is (a) no net charge is enclosed by the surface.
According to Gauss’s law, the net electric flux through a closed surface is given by
Φ = Qenc/ϵ0
. If the flux is zero, the net charge enclosed (Qenc) must also be zero, meaning either no charge is inside or equal positive and negative charges cancel out.
The correct answer is (d) 1/2 µF. For capacitors in series, the equivalent capacitance is given by: 1/Ceq = 1/C₁ + 1/C₂ + 1/C₃ Substituting C1 = 2 pF, C₂ = 3 pF and C₃ = 6 pF, we get Ceq = 1 pF = 1/2 µF. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-2/
