Which statement is true about the picture above?
a) the spheres have only weight but no mass
. b) the 40 newton sphere has the greatest gravitational force. eliminate
c) the smaller the weight, the greater the gravitational force.
d) although the weights of the spheres are different, the gravitational forces are the same.

i think its c if i'm wrong

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
