In an electric field, the lines on the left have twice the separation as those on the right. (a) If the magnitude of the field at A (particle in the field with lesser separated lines) is 58 N/C, what is the magnitude of the force on a proton at A? (b) What is the magnitude of ...

What must the charge (sign and magnitude) of a particle of mass 1.48g be for it to remain stationary when placed in a downward-directed electric field of magnitude 670N/C ? What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude...

Suppose a single electron orbits about a nucleus containing two protons (+2e), as would be the case for a helium atom from which one of the naturally occuring electrons is removed. The radius of the orbit is 2.26 10-11 m. Determine the magnitude of the electron's centripetal...
