Homework Statement
What is the electric field midway between an electron and a proton separated by 0.8 nm?
Homework Equations
E=kQ / r^2 . 9E9 x 1.6 E-19 / .(.8E-9)^2
The Attempt at a Solution
Any help would be nice!
An electric field is a physical quantity that describes the influence of electric charges on each other. It is a vector quantity, meaning it has both magnitude and direction.
The magnitude of the electric field midway between an electron and proton is given by the equation E = kq/r^2, where k is the Coulomb's constant, q is the magnitude of the charge, and r is the distance between the two charges. Since the charges of an electron and proton are equal in magnitude, the electric field midway between them will be equal to zero.
This is because the electric field is a vector quantity and the fields created by the electron and proton point in opposite directions. At the midpoint, these fields cancel each other out, resulting in a net electric field of zero.
No, the electric field midway between an electron and proton will always be zero. This is because the charges are stationary and not moving, so there are no changing electric or magnetic fields that could create a non-zero field.
The direction of the electric field is always from positive to negative charges. In the case of an electron and proton, the direction of the electric field at the midpoint will point from the proton towards the electron.
