suppose you pass light from a he-ne laser through two slits seperated by 0.0100 mm and find that the third bright line on a screnn is formed at an angle of 10.95 degrees relative to the incident beam. what is the wavelength of the light?

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
