Four 75kg spheres are located at the corners of a square of side 0.60m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.
The ions will separate until they make an electric field that exactly balances the magnetic force. This electric field produces a voltage that can be measured. a. What force is felt by a singly ionized (+) sodium ion?

What is the magnetic potential energy of a 2 cm diameter circular loop carrying a 1A current when placed in a 2 T uniform magnetic field after reaching its stable equilibrium position?
A tube, open at only one end, is cut into two shorter (nonequal) lengths. The piece that is open at both ends has a fundamental frequency of 428 Hz, while the piece open only at one end has a fundamental frequency of 684 Hz. What is the fundamenta
Express the result for the range as a percentage of the actual maximum range of this weapon, which is 30 km for unassisted ammunition.
A block on a spring is pulled ot the right and released at t = 0 s.It passes x = 3.1cm at t = 0.685s, and it passes x = -3.01 cm at t = 0.886s. a. What is the angular frequency?
Two points charges attract each other with an electric force of magnitud F. If one charge is reduced to one third its original value and the distance between the charges is doubled, what is the resulting magnitud of the electric force between them
A hundred volt potential difference is suddenly applied to the initial uncharged plates through a 1000 ohm resistor in series with the deflection plates. How long does it take for the potential difference between the deflection plates to reach 95
