Acharged wire of negligible thickness has length 2l units and has a linear charge density λ. consider the electric field e-vector at the point p, a distance d above the midpoint of the wire. the field e-vector points along one of the primary axes, ywhat is the magnitude e of the electric field at point p? throughout this part, express your answers in terms of the constant k, defined by k=1/(4πε)

Explanation:

Given that

Length= 2L

Linear charge density=λ

Distance= d

K=1/(4πε)

The electric field at point P

So

Now by integrating above equation

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
