Options
E ≠ 0 and V ≠ 0
E = 0 and V = 0
E ≠ 0 and V = 0
E = 0 and V ≠ 0
MCQ
Fill in the Blanks
Solution
Three Charges 2q, -q and -q lie at vertices of a triangle. The value of E and V at centroid of triangle will be E ≠ 0 and V = 0.
Explanation:
Net E F I at G ≠ O
Net Potential at G,
V = `("K"_2"Q")/"r" - "KQ"/"r"`
`= - "KQ"/"r"`
= 0
