The figure shows a particle that carries a charge of q0 = -2.81 X 10-6 C. It is moving along the +y axis at a speed of v = 4.97 X 106 m/s. A magnetic field B of magnitude 3.48 X 105 T is directed along the +z axis, and an electric field E→ of magnitude 140 N/C points along the -x axis.
Determine (a) the magnitude and (b) direction (as an angle within x-y plane with respect to + x -axis in the range (-180 degree , 180 degree ]) of the net force that acts on the particle.
To focus a camera on objects at different distances, the converginglens is moved toward or away from the image sensor, so a sharpimage always falls on the sensor.
A particle of charge +4.31 × 10-6 C is 10.1 cm distant from a second particle of charge -1.95 × 10-6 C. Calculate the magnitude of the electrostatic force between the particles
