two identical metal balls are mounted on insulting rods. ball a gas a charge of +q and ball b is initially charged. ball a is touched to ball b. at the end of the experiment, what is the charge on ball a two identical metal balls are mounted on insulting rods. ball a gas a charge of +q and ball b is initially charged. ball a is touched to ball b. at the end of the experiment, what is the charge on ball a two identical metal balls are mounted on insulting rods. ball a gas a charge of +q and ball b is initially charged. ball a is touched to ball b. at the end of the experiment, what is the charge on ball aExplanation / Answer
The charge on ball A is +q and ball B is neutral charge.
When the balls are tiuch each other, then the charge distributed among two balls equally, according to law of conservation of charge.
Hence, the charge on each ball is,
qA = qB = (q+0)/2 =q/2
Therefore, the charge on A is q/2
