Answer:
An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.
Answer:
Half as much as it was
Explanation:
According to Charles law
PV = k
P is the pressure
V is the volume
If PV= k, then P1V1= P2V2
P1 and P2 are the initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given
V1 =11.2litres
P1 = 0.860atm
If the volume is doubled, V2 = 2(11.2) = 22.4litres
Get P2
P2 = P1V1/V2
P2 = 0.860×11.2/22.4
P2 = 0.860/2
P2 = P1/2 (since P1 =0.860)
P2 = 1/2 P1
Hence the pressure becomes halved if the volume is doubled
