Two charges $q_{1}$ and $q_{2}$ are located at points O and M on the x-axis, respectively. The relationship between the potential $φ$ along the x -axis and position is shown in the figure. Then :

Options:

Answer:

Solution:

$E_{x} = - d φ / d x$ ; slope at C is zero but at N is not. (A) false.

C lies outside the charges; field cancellation there requires $∣ q_{1} ∣ > ∣ q_{2} ∣$ . (B) false.

From N to C the potential rises; from C to D it falls. $W = - q Δ φ$ for a negative charge.

Work is first positive, then negative: (D) true. (C) false.
