Question

A small metal ball is brought into contact alternatively with points A, B and C of the charged body shown in figure. After each contact the charge of the ball is determined approximately by touching it against an electroscope. If qA, qB and qC are the charges, then (A) qA > qB > qC (B) qA < qB < qC (C) qA=qB, qC=0 (D) qA=0, qB=qC

The charge density nearby A is greatest and at C, it is least.

Q. A small metal ball is brought into contact alternatively with points $A, B$ and $C$ of the charged body shown in figure. After each contact the charge of the ball is determined approximately by touching it against an electroscope. If $q_{A}, q_{B}$ and $q_{C}$ are the charges, then

$q_{A} > q_{B} > q_{C}$

$q_{A} < q_{B} < q_{C}$

$q_{A} = q_{B}, q_{C} = 0$

$q_{A} = 0, q_{B} = q_{C}$

The charge density nearby $A$ is greatest and at $C$ , it is least.

Q. A small metal ball is brought into contact alternatively with points A,B and C of the charged body shown in figure. After each contact the charge of the ball is determined approximately by touching it against an electroscope. If qA​,qB​ and qC​ are the charges, then

qA​>qB​>qC​

qA​<qB​<qC​

qA​=qB​,qC​=0

qA​=0,qB​=qC​
