Cevap
To determine the magnitude of the electric field directly above an isolated charge, we use the formula for the electric field due to a point charge:
where:-
is Coulomb's constant (
),-
is the magnitude of the charge (
),-
is the distance from the charge to the point where the electric field is being calculated (14.8 cm = 0.148 m).Plugging in the values:
First, calculate the numerator:
Next, calculate the denominator:
Now, divide the numerator by the denominator:
So, the magnitude of the electric field directly above the charge is:
