Problem 1:
Two infinite lines of charge with equal linear charge densitiesl (C/m) are placed along the x and yaxis. Derive an expression for the magnitude of the electricfield at an arbitrary point (x, y).
Problem 2:
Use Gauss’ law
Where g is the gravitational field strength, G is the gravitational constant, and m is the mass enclosed by the Gaussian surface. Show that one can obtain Newton’slaw of gravitation from this expression.
