Why does the weaker force of gravity dominate over electrical forces for astronomical objects?

Forces of gravity depend on quantities of mass, whereas electrical forces depend on quantities of net charge.

If gravitational forces dominate over electrical forces, it can only be because the amounts of net charge involved are much much much much much smaller than the amounts of mass involved.

What I'm saying is ... this doesn't mean that there aren't huge amounts of electric charge present in stars, planets, comets, and other astronomical objects.  But most of the charges are BALANCED ... there are equal amounts of positive and negative charge present in the same object, and there's very little of either kind left over, to be attracted or repelled by other objects.

neither accurate nor precise.

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
