Question

Three Charges 2q, -q and -q lie at vertices of a triangle. The value of E and V at centroid of triangle will be ______.

विकल्प

• E ≠ 0 and V ≠ 0

• E = 0 and V = 0

• E ≠ 0 and V = 0

• E = 0 and V ≠ 0

Answer 1

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
