Here it is. I used the surface charge density σ as q/Area, and then wrote it out in terms of q at the end
Answer: The potential difference between the plates = 0.4061V
Explanation:
Given that the
Electric field strength E = 155 N/C
Distance d = 0.00262 m
From the definition of electric field strength, is the ratio of potential difference V to the distance between the plates. That is
E = V/d
Substitute E and d into the above formula
155 = V/0.00262
Cross multiply
V = 155 × 0.00262
V = 0.4061 V
The potential difference between the plates is 0.4061 V
Bro sorry I don’t know these answer but keeep trying
Answer: a magnetic field is created by moving electric charges
Density of cylinder is 4.82 g/cm³.
<h3>What is density of a substance?</h3>
Density is the ratio of the mass and the volume of a substance
The density of the cylinder is:
mass of cylinder = 50.12 g
volume of cylinder = πr²h
r = 1.62/2 = 0.81 cm
h = 5.04 cm
volume of cylinder = 22/7 * 0.81² * 5.04
volume of cylinder = 10.39 cm³
Density of cylinder = 50.12 g/10.39 mL
Density of cylinder = 4.82 g/cm³
In conclusion, density of a substance is the ratio of mass and volume of the substance.
