A 4. 0 nc positive point charge is located at point a in the figure. (figure 1) what is the electric potential at point b?.
algol [13]

The electric potential at point b experienced by the charge cab be determined using the formulas given.

<h3>Electric potential</h3>

The electric potential of a point charge is the work done in moving the charge from infinity to certain point against the electric field.

V = Ed

V = (F/q)d

V = (Fd)/q

where;

  • V is the electric potential
  • F is electric force
  • E is the electric field
  • q is the charge

Thus, the electric potential at point b experienced by the charge cab be determined using the formulas given.

What is the difference between displacement and distance travelled​
IrinaK [193]
Displacement in Space
It is the length of a body's real route. It is the shortest distance between the body's final and beginning positions.
It's a number with a scalar value. It's a quantity with a vector.
It can't possibly be negative. It might be a negative number, a zero number, or a positive number.

What is the current in milliamperes produced by the solar cells of a pocket calculator through which 3.70 C of charge passes in
Kaylis [27]

Answer:

Current flowing in the cell will be equal to 0.1284 mA

Explanation:

We have given charge q = 3.70 C

And time through which charge is flowing = 8 hour

We know that 1 hour = 60 minutes, and 1 minute = 60 sec

So 1 hour = 60×60 = 3600 sec

So 8 hour = 8×3600 = 28800 sec

We know that current is rate time rate of flow of charge

So current i=\frac{q}{t}=\frac{3.70}{28800}=1.284\times 10^{-4}A=0.1284mA

So current flowing in the cell will be equal to 0.1284 mA
