A charged particle is moving through a constant magnetic field. Does the magnetic field perform work on the charged particle

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

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

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
