The second most common type of the condition is known as ocular albinism, in which only the eyes lack color; skin and hair are normal. There are five forms of ocular albinism; some types cause more problems-especially eye problems-than others.
Electric Field at the Center of a Semicircle. electric field of a semicircle on a point The rectangular part of the field is 100 yds long and the diameter of each semicircle is 44 yds Electric magnitude of semicircle
The electric field a distance r away from a point charge Q is given by: Electric field from a point charge : E = k Q / r2. The electric field from a positive charge points away from the charge; the electric field from a negative charge points toward the charge. Like the electric force, the electric field E is a vector. If the electric field at a particular point is known, the force a charge q experiences when it is placed at that point is given by : F = qE. If q is positive, the force is in the same direction as the field; if q is negative, the force is in the opposite direction as the field.
