A force of 5.78x10^-16N acts on an unknown particle moving at an angle of 90 degrees through a magnetic field. if the velocity of the particle is 5.65x 10^4 m/s and 3.20x10^-2T, how many elementary charges does it carry
Determine the electric field and the potential at any point in space produced by a spherical
crown where the internal radius is R1 and the external one R2, with a total charge Q, for the
following cases: (a) non conducting and an uniform charge distributed throughout the volume;
and (b) metallic and on electrostatic equilibrium. Particularize the results for a solid sphere with radius R
We have an isolated spherical conductor whose radius is R1 = 4 cm, and whose
potential is 9000 V referring to ground. After, it is surrounded with a concentric spherical
conducting layer, with inner radius R2 = 8 cm and exterior one R3 =10 cm, isolated and with
null total charge. Determine charges and potentials on the inner conductor, as well as the
conducting layer, for the following cases:
a. Inner conductor and conducting layer isolated.
b. If the conducting layer is connected to ground.
Determine the electric field produced on any point in space by a very long line
(infinite) charged with a uniform density λ
Calculate much net Work per unit charge would it take to move a particle from a -15 V potential
to a +10 V potential? Does the path of the motion matter?
The heat from the sun travels to the earth through the process of?
Can i know if there is any suggestion of new electromagnetic waves application to be used in this pandemic era
A wire with resistance of 8.0ohms is drawn out through a die such that it’s new length is twice it’s original length. Find the resistance of the longer wire assuming that the resistivity and the density of the material of the wire are unchanged during the drawing process
Two parallel plates have equal and opposite charges. When space
was evacuated, the electric field was 2.80 x 105 V/m. When it
was filled with a dielectric material, the electric field was 1.20 x
105 V/m. What is the dielectric constant? What is the material?
If the value you computed has an SI unit of 𝐶²m²/kgm², the quantity could be
a. potential difference c. electric field
b. dielectric constant d. capacitance
