A particle with charge q and mass m moves in static external fields E0(7) and Bo(r). If Φ。(%) is the electrostatic potential at the position of the particle, and there is negligible radiation, the usual statement of conservation of energy for this system is Show that this equation agrees with the power balance represented by Poynting's theorem only if one adds to the latter the power supplied by an external energy source to maintain Eo() and Bo(F) against the work...
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground.
A student throws a water balloon with speed vo from a height h = 1.52 m at an angle θ=39° above the horizontal toward a target on the ground. The target is located a horizontal distance d = 7.5 m from the student's feet. Assume that the balloon moves without air resistance. Use a Cartesian coordinate system with the origin at the balloon's initial position. Part (a) what is the position vector, Rtarget that originates from the balloon's original position and...

A satellite of mass m is traveling at speed vo in a circular orbit of radius ro under the gravitational force of a fixed mass M at point O. At a certain point Q in the orbit (see the figure below) the direction of motion of the satellite is suddenly changed by an angle α without any change in the magnitude of the velocity. As a result the satellite goes into an elliptic orbit. Its distance of the closest approach...

feet per second and in miles per second 18 An object of mass m is moving horizontally through a medium which resists the motion with a force that is a func- tion of the velocity; that is, d's dv f(v) dt =m dt2 where v = s(1) represent the velocity and at time , respectively. For example, v(t) and s position of the object think of a boat moving through the water. (a) Suppose that the resisting force is proportional...

Three identical point point charges, each of mass m and charge q,
hang from three strings as pictured below, the length of left and
right string are L and the angle is θ. Determine the value on terms
of m, L,θ
So the answer has to be q=(4mg L^2sen^2 θ tanθ/5K)^(1/2) but I
