is enclosed by a surface S. the flux crossing the S is Question 2
A charge is uniformly distributed throughout the sphere of radius 
. Taking the potential at infinity as zero, the potential at 
is
. Taking the potential at infinity as zero, the potential at is Question 3
A thin soap bubble of radius R = 1 cm, and thickness a = 3.3 µm (a<<R)is at a potential of 1 V with respect to a reference point at infinity. The bubble bursts and becomes a single spherical drop of soap (assuming all the soap is contained in the drop) of radius r. The volume of the soap in the thin bubble is 4πR2a and that of the drop is 
. The potential in volts, of the resulting single spherical drop with respect to the same reference point at infinity is __________. (Give the answer up to two decimal places.)
