Question

What is the electric potential energy of a 4. 0 uc charge placed at that point where the electric potential at that point in space is 8 v?

Answer 1

The electric potential at that point in space is 8 v is 32uj

what is electric potential energy?

Potential energy is the energy within an object relative to its position and proximity to other objects within a field.

The electric potential of a point charge is V=kQ/rV=kQ/r , or V = k Q / rV=kQ/r . Electric potential is a scalar while the electric field is a vector. While the total electric field can be computed by adding individual fields as vectors, the voltage resulting from a collection of point charges can be calculated by adding voltages as integers.

It is decided to set the potential at infinity to zero.

but V for a point charge reduces with distance while decreasing with distance squared. Remember that the electric field E is a vector, but the electric potential V is a scalar with no direction.

The electric energy is (8×4)=32 uj

Answer 2

The electric energy is 32 uj

The electric potential of a point charge is $V=kQ/r$, or $V = k Q / r$. Electric potential is a scalar while the electric field is a vector. While the total electric field can be computed by adding individual fields as vectors, the voltage resulting from a collection of point charges can be calculated by adding voltages as integers.

It is decided to set the potential at infinity to zero. $E=Fq=kQr^2$, but V for a point charge reduces with distance while decreasing with distance squared. Remember that the electric field E is a vector, but the electric potential V is a scalar with no direction.
