In the figure below, L = 1.0 mm, q\(_1\) = +3 nC, q\(_2\) = -2 nC, and q\(_3\) is +4 nC. Find the magnitude and direction of the net electrostatic force on q\(_3\)
Two dipoles are placed a distance, d = 0.05 m, from the point A (labeled in red). The distance between dipoles is s = 0.01 m. Each dipole consists of a positive and negative charge of \(\pm\)2 nC. Find the electric field at point A.
A very long thin wire carries a line charge density, \(\lambda\) = 361.0 \(\frac{nC}{m}\). Find the electric potential difference between points 3.0 m and 6.0 m on a perpendicular radius to the axis of the wire, provided the perpendicular radius is not near either end of the wire. (this problem requires calculus)
How do magnets work?
The circuit below is a square with sides L and is placed in a magnetic field directed into the screen. Attached to the circuit are two light bulbs of resistance R \(\Omega\). The magnetic field is described by the function B(t) = at + b. What is the current in the circuit and in what direction does it flow. Also how much power is dissipated in light bulb 1.
A concave mirror has a focal length of 40 cm. Determine the object position for which the resulting image is upright and 4 times the size of the object.
A “F” note has a wavelength of 98.8 cm. Calculate its frequency.
In the figure below, A = 3 cm, B = 1 cm, q\(_1\) = +15 nC, q\(_2\) = -5 nC, and q\(_3\) is -10 nC. Find the magnitude and direction of the net electrostatic force on q\(_3\)
Point A is a distance d = 0.5 m from the center of a charged rod. The rod has a charge of + 1 nC and is X = 4 m long. Find the electric field at point A.
The figure below shows two capacitors. The capacitor on the left has a uniform electric field, \(\vec{E}_1\) = N/C. The capacitor on the right has a uniform electric field, \(\vec{E}_2\) = N/C. If we define the point directly between A and B to be the origin, then point A is at and point B is at . Find the potential drop on the path from A to B. If a proton traveled from rest at point A to point B, what would be its kinetic energy at point B?
