1) Consider a spherical Gaussian surface and three charges: q1 = 1.62?C , q2 = -2.45?C , and q3 = 3.57?C . Find the electric flux through the Gaussian surface if it completely encloses
(a) only charges q1 and q2,
(b) only charges q2 and q3, and
(c) all three charges.
2) A proton is released from rest in a uniform electric field of magnitude 1.00×105 N/C . Find the speed of the proton after it has traveled
(a) 1.10cm and
(b) 13.0cm
A rock is thrown vertically upward from ground level at time t = 0. At t = 1.9 s it passes the top of a tall tower, What is the height of the tower
Bacteria vary somewhat in size, but a diameter of 2.00?m is not unusual, What would be the volume (in cubic centimeters)
Why three points? Would two have been enough? Describe what changes would occur, if any, in the electric field pattern and in the equipotential curve you measured if the magnitudes of your three charges were increased, all by the same factor.
A uniform solid sphere of radius 0.503 m and mass 15.7 kg turns counter clockwise (when viewed from above) about the vertical axis through its center. Find its vector angular momentum when its angular speed is 3.08 rad/s. Wouldn't you use the formula..
The shaft shown below has a solid round cross-section & is supported by bearing at A & B. Find the location of maximum bending stress in the shaft.
An electron starts from rest 75.5 cm from a fixed point charge with Q = -0.150 µC. How fast will the electron be moving when it is too far away.
A 0.100g plastic bead is charged by the addition of 1 x10^10 excess electrons (i.e. so the bead becomes negatively charged). What electric field (magnitude and direction) will cause the bead to hang suspended in the air?
Use approximate relationships to find the electric field at a point 4 cm from the axis, measured radially outward from the midpoint of shell.
While moving down the track at 10.0 m/s, you uniformly accelerate to 32.0 m/s in 10 s. Illustrate what is the average net force that you have applied to the car during the 10 s interval?
A star ship is circling a distant planet of radius. The astronauts determine that the acceleration because of gravity at their altitude is half the value at the planet's surface. How far above the surface are they orbiting? Your reply would be a m..
A charged particle A exerts a force of 2.69 ?N to the right on charged particle B, when the particles are 14.0 mm apart. Particle B moves straight away from A to make the distance between them 17.0 mm. What vector force does it then exert on A?
What is the final speed of the crate after being pulled. On a very muddy football field, a 100 linebacker tackles an 80 halfback. Immediately before the collision, linebacker is slipping with a velocity of 8.5 north and the halfback is sliding with..
