Question

Two similar conducting spheres having charges –3 μC the +5 μC are connected by a conducting wire for a short while, then

Options:

3.125 × 1013 electrons will flow from negatively charged sphere to positively charged sphere

2.5 × 1013 electrons will flow from positively charged sphere to negatively charged sphere

Final charge on each sphere will be +1 μC each

Both (2) and (3)

Answer 1

Answer:

Final charge on each sphere will be +1 μC each

Explanation:

(1) q = q1 + q2 = – 3 μC + 5 μC = 2 μC

This 2 μC charge will divide equally between the sphere the 1 μC each.

(2) 4 μC coulomb charge will flow

⇒ Number of electron (n)

4x10^-6/1.6x10^-19 = 2.5 × 1013

From negatively charged sphere to positively charged sphere.
