Q. A uniform circular ring of charge Q= 5.60 microCoulombs and radius R= 1.30 cm is located in the x-y plane, centered on the origin.
What is the magnitude of the electric field E at point P, located at z= 2.40 cm? 5.942×107 N/C
Consider other locations along the positive z-axis. At what value of z does E have its maximum value?
What is the maximum value of E on the z-axis?
If z << R then E is proportional to z. (You should verify this by taking the limit of your expression for E for z << R.) If you place an electron on the z-axis near the origin it experiences a force Fz= -kz, where k is a constant. Obtain a numerical value for k.
What is the frequency of the small axial oscillations that the electron will undergo if it is released along the z-axis near the origin?

The two blocks are on frictionless inclines and are in static equilibrium. The block on the left has a mass of 49 Kg, and the block on the right has a mass of n3 Kg. If the left incline has the length of n1 meters, and the right incline the length of..
If you weigh 690 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 25.0 km.
A man sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. The combined mass of the man and chair is 86 kg. With what force magnitude should the man pull on ..
A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is ..
