Question

15. Two spherical conductors have a total charge Q. The radii of the spheres are c and d, where c>d. Which sphere has the higher potential?
a. The sphere of radius c
B. The sphere of radius d
C. Both have the same
potential
18. When two capacitors are connected in series, the charge on the capacitors
a. is larger on the larger capacitor.
b. is smaller on the larger capacitor.
c. is the same on both capacitors.
19. When two capacitors are connected in parallel, the charge on the capacitors
a. is larger on the larger capacitor.
b. is smaller on the larger capacitor.
c. is the same on both capacitors.

explain answer please

Explanation / Answer

15) b (the charges are closer to each other in a small sphere) 18) c (Since their plates will be connected, the charge will be same) 19) a (since Q= CV, V is same, larger the C larger the Q)
