denote Coulomb's constant (
.) Let the magnitude of that point charge be 
. At a distance of 
from this charge, the electric field due to this charge would be:
.
.
:

: 
.
:
.
point charge here is positive, the electric field of this charge would repel other positive point charges. Hence, the electric field around this 
point charge at any point in the field would point away from this charge.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf Īµ. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 Ļ, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 āc, and the temperature at the surface is 23.0 āc. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
