Two 2µF capacitors are connected in Parallel. The combination is then connected in series with a 12.O V battery and a 8.0µF capacitor. The energy stored in the 8.0pF is

frequency or wavelenth of em radiation in a vacuum

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
