Question

3.
Equipotential lines and electric field lines are always
disjoint.
parallel.
perpendicular.
None are correct.

Answer 1

disjoint...
though u may get correct ans for ur homework(i presume) here but for actual understanding this actually affect ur reasoning ability to get ans easily...visit the video by prof lewin and study it before attempting these...hopefully,u may not need to ask them here...

Answer 2

sorry its perpendicular i misreaad..

Answer 3

We have a parallel plate capacitor with two plates containing charges + Q and -Q a distance d = 1.60 cm apart. We release a proton from rest at point A, just above the lower plate. At point B, just before the proton strikes the upper plate, the proton has a kinetic energy of 1.43 × 10-18 J. A proton has a mass of 1.67 × 10-27 kg and a charge of 1.60 × 10-19 C. What is the magnitude of the electric field between the plates (in V/m)?
