the large horizontal metal plate are separated by 4mm .the lower plate is at a potential pg -6v what potential should be applied to the upper plate to create an electric field of strength of 4000 Vm-1 upward in space between plate

the results is a decrease in air temperature with an increase of altitude.

explanation:

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
