Do black holes pull you in at the speed of light? Or is it the black holes gravity that pulls you in? If so... how fast does it pull you in?

Black pull by its gravity but almost at the speed of light. It pulls by 56,000 miles per second.

c.the charges if the proton and electron and gravity

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
