two slits are spaced 0.3 mm apart and are placed 50 cm from a screen. what is the distance between the second and third maxima when the illuminating light has a wavelength of 6000 å?

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
