A parallel-plate capacitor is formed of two 10 cm x10 cm plates spaced 1.0 cm apart. The plates charged to +/-1.0 nC. An electron is shot through a very small hole in the positive plate.
a) Find the magnitude and direction for the electric field E generated by the parallel plate capacitor.
b) What is Fel on the electron inside the parallel plate capacitor.
c) What is the slowest speed the electron can have if it is to reach the negative plate?
The tension Tu in upper (taut) segment of the belt is 170 N, and flywheel has a clockwise angular acceleration of 1.67 rad/s2. Find out the tension in the lower (slack) segment of the belt.
Find out the angle theta_1 through which the flywheel will have turned during the time it takes for it to accelerate from rest up to angular velocity omega_1.
What can you conclude about the resulting displacements?
Two very small spheres, each with a mass m = 1.5 g, are suspended from a common axis by insulating threads of length L= 6.0 cm, What is the magnitude of the unknown charge q
Charges q and Q are placed on the x axis at x = 0 and x = 2.0 m, respectively. If q = -40 pC and Q = +30 pC, define the net flux through a spherical surface (radius = 1.0 m) centered on the origin.
An electric motor operates at 6 volts. In order to lift a mass of 1 kilogram a distance of 2 meter in 3 seconds, how much current in amps must the motor draw? (Assume the motor is 100% efficient.)
A fish swimming in a horizontal plane has a velocity vi = (3.3i + 1.6j) m/s at a point in the ocean where the position relitive to a certian rock is ri = (10.5i - 3.9j) m. After the fish swims with a constant acceleration for 20.6 s, it's velocity..
