An electron is located on the x axis at x0 = -9.31×10-6 m. find the magnitude and direction of the electric field at x = 9.39 ×10-6 m on the x axis due to this electron. what is the magnitude in n/c? is the direction positive x direction, negative x direction, or neither.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

force tends to be low and long diustance masses are high

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
