A set of charges are arranged in the following way: a 10.0 nC (nanocoulomb) positively charged particle sits at the origin of a coordinate system. A second positively charged particle of 5.00 nC lies along the (positive) x-axis a distance of 0.250 m from the origin. A third and negatively charged particle of -2.50 nC lies a distance of 0.150 m from the origin on the negative y-axis.
A. Sketch a diagram of this charge configuration
B. Calculate the electric field the second and third charges create at the origin.
C. Find the magnitude and direction of the force on the particle at the origin.
For a particular collision you detect the emitted products and find 15 protons, 2 antiprotons, 6 positrons, and 25 neutral particles. How many electrons are also emitted?
What is the magnitude and direction of the magnetic field
what is the coefficient of kinetic friction between the box and the tabletop.
A 0.30 kg softball has a velocity of 12 m/s at an angle of 35° below the horizontal just before making contact with the bat. The ball leaves the bat 2.0 ms later with a vertical velocity of magnitude 10 m/s. What is the magnitude of the average f..
An electric field E with an average magnitude of about 150 N/C points downward in the atmosphere near Earth's surface, What charge (both sign and magnitude) must be used
A 79kg person holds out his arms so that his hands are 1.6m apart. Normally, a person's hand makes up about 1% of his or her body weight. For round numbers, we shall assume that all the weight of each hand is due to the calcium in the bones.
A gas is compressed at a constant pressure of 0.800 atm from 12.00 L to 3.00 L. In the process, 380 J of energy leaves the gas by heat. (a) What is the work done on the gas? J (b) What is the change in its internal energy?
Express the power in terms of some or all of the variables given in the problem introduction.
Assume the car is moving at 72 km/hr when the brake pedal is applied. Assume that the radius of the wheel is 15 cm. What is the maximum power.
Following the procedure in the video, create three traces of the pendulum motion of the cup. Compare the three traces for amplitude, wavelength, and frequency.
Calculate the x-component of vector. A uniform electric field of magnitude 375 N/C pointing in the positive x-direction acts on an electron, which is initially at rest.
A student pulls a box of books on a smooth horizontal floor with a force of 100 N in a direction of 37 degrees above the horizontal. If the mass of the box and the books is 40 kg, what is the normal force on box? a. 332 N b. 312 N c. 392 N d. 292 N
