Question
The radii of two metallic spheres are 5 cm and 10 cm and both carry equal charge of 75μC. If the two spheres are shorted then charge will be transferred -
Options
A.25 μC from smaller to bigger
B.25 μC from bigger to smaller
C.50 μC from smaller to bigger
D.50 μC from bigger to smaller
Solution
(A) Qt = Q1 + Q2 = 150μC
⇒ Q1′ = 50μC
Q2′ = 100μC
25μC charge will flow from smaller to bigger sphere .
⇒ Q1′ = 50μCQ2′ = 100μC
25μC charge will flow from smaller to bigger sphere .
