Two parallel, infinite, nonconducting plates are 4.53 cm apart and have charge distributions of +2.25 μC/m2+2.25 μC/m2 and –2.25 μC/m2–2.25 μC/m2 . (a) What is the magnitude of the force on an electron in the space between the plates? (You may enter your calculation using scientific notation.)  N (b) What is the magnitude of the force on an electron located outside the two plates near the surface of one of the two plates?  N

An x m high, 7 m wide rectangular plate fully emerges in the freshwater channel, as shown in the figure. The plate is hinged about a horizontal axis along its upper edge through point A and is restrained from opening by a fixed ridge at point B. Determine the force exerted on the plate by the ridge in kN.     P.S: The drawing is not drawn on an accurate scale.Here, x=9 m

A uniform rod of length L and weight W is placed on a fulcrum a distance of 0.4L from the left end. On the left end is placed a mass of weight 2W and on the right end a vertical force F is applied to keep the system in balance. What are the magnitude and direction of the force F?Select one:a.b.c.d.
