What is its final kinetic energy
A proton is initially at rest at a point where the potential is 499 V. Some time later the proton is at a point where the potential is 211 V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy?.

The Nichrome wire is l =6 cm long and has radius r=1 mm.3 Nichrome has 9 × 1028 mobile electrons/m and an electron mobility of 7 × 10^-5 (m/s)/(V/m). What is the magnitude of the electric field in the copper wire?
The distance of separation, measured between their centers, is 3.84x10^8. Locate the center of mass of the earth-moon system as measured from the center of the earth.
Assuming that the torque is unchanged, but the mass of the wheel is doubled and its radius is halved. How will this affect the angle through which it rotates before coming to rest?
A rectangular plate has a length of (20.3 ± 0.2) cm and a width of (8.6 ± 0.1) cm. Calculate the area of the plate, including its uncertainty.
The electron's acceleration is due to two electric forces parallel to the x axis: , and , which points in the -x direction. Find the magnitudes of (a) the net force acting on the electron and (b) the electric force.
A 150-g block on the end of a spring with a spring constant of 35 N/m is pulled aside 25 cm and released from rest. In the electrical analog the maximum charge on the capaciteris 0.25 C.The maximum current in the LC circuit is

Yusef pushes a chair of mass m = 45.0kg across a carpeted floor with a force F? p (the subscript 'p' here is lowercase and throughout the question) of magnitude Fp = 144N directed at θ = 35.0degrees below the horizontal (Figure 1) . The magn
Determine the force on the table as a function of the distance x that the upper end has fallen. Assume the table is energy absorbing -- the chain does not bounce as it hits the table. What is the force when one-half of the chain lies on the table?
