Auniform electric field exists in a region between two oppositely charged plates. an electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate. 2.6 ã away, in a time 1.5 x 10 a s (a) what is the speed of the electron as it strikes the second plate? (b) what is the magnitude of the electric neo

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
