Answer question 11

Dear Student,

(a)  1 and 2 are negatively charged particle ( electrons ) as they are deflected towards + plate
     3 is positively charged particle( possibly proton )

charge to mass ratio is directly proportional to the virtical displacement
Thus particle 1 has highest q/m ration


Capacitance of spherical conductor is= QVV=Q4πε0R  or C=4πε0RC1=4πε0R  while C2=8πε0R  so C2=2C1

Due to paucity of time we cannot solve all questions. Please make a separate post.
