A point charge of 7nC is at a fixed location of (4mm, 3mm, 0). Another point charge of -5nC is located at a fixed position of (3mm, 4mm, 0). What will be the force acting on an electron placed in the origin of the coordinate system

An object in mechanical equilibrium is an object

Is the portion of the electromagnetic spectrum that has a frequency just above that of visible light.

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
