Vedclass · Answer

(B) Statement $A$ is correct: The tangent drawn to a line of force at any point gives the direction of the electric field at that point.Statement $B$ is incorrect: Electric field lines originate from positive charges and terminate at negative charges. They do not form closed loops,unlike magnetic field lines.Statement $C$ is correct: The force on a charge $q$ in an electric field $E$ is given by $F = qE$. If $q$ is negative,the force $F$ is in the direction opposite to $E$.Statement $D$ is correct: Two electric field lines can never intersect,because if they did,there would be two directions for the electric field at the point of intersection,which is physically impossible.

$A$ $6 \mu C$ charge is placed at the centre of a cube. What will be the electric flux through each face of the cube? (Take $\frac{1}{4 \pi \epsilon_0} = 9 \times 10^9 \ Nm^2 C^{-2}$)

Assertion: Four point charges $q_1, q_2, q_3$ and $q_4$ are as shown in the figure. The flux over the shown Gaussian surface depends only on charges $q_1$ and $q_2$.
Reason: Electric field at all points on the Gaussian surface depends only on charges $q_1$ and $q_2$.
