For a rhombus with diagonals of length 6 cm and 8 cm. (a) Find the length of each side of the rhombus. (b) Find the area of the rhombus. (c) Explain why a circle can be inscribed inside a rhombus (any rhombus). A circle inscribed in a polygon means each side of the polygon is tangent to the circle. Use what you know about why any triangle has an inscribed circle. (d) Find the exact area of the inscribed circle in terms of π.

Consider a rhombus with side of length L. The rhombus has two
pair
of equal interior angles. Label one of these pair θ and the other
φ. Four
identical, positive point charges, q are placed on the vertices of
the rhombus.
Draw the configuration.
a) Obtain a symbolic expression for the electric field at one of
the vertices
(your choice) and then at an adjacent vertex (Do you now know the
electric
field at all of...
