Practicing Success
Two point charges $q_1=2 \mu C$ and $q_2=-2 \mu C$ are placed 20 cm apart from each other. Point 'a' is 5 cm away from q, on the line joining $q_1$ and $q_2$ on the side opposite to $q_2$. Point 'b' is 5 cm away from $q_2$, on the line joining $q_1$ and $q_2$, opposite to $q_1$. Point 'c' is at a perpendicular distance of 10 cm from the centre point D of the line joining $q_1$ and $q_2$. Identify the correct statement depicting the situation. |
Point C and D are equipotential Potential at point a, $V_a<V_b$, potential at point b Potential at point a, $V_a<V_c$, potential at point c Potential at point D, $V_D>V_b$ potential at point b |
Point C and D are equipotential |
The correct answer is Option (1) → Point C and D are equipotential Point C and D are equidistant from $q_1$ and $q_2$. So net potential on C and D is zero. Hence option (1) is correct. *Option (4) is not clear (There must be an error in option 4). |
