Se tienen dos cargas puntuales de q1 = -3 μC y q2 = 6 μC separadas a una distancia de 8 cm como se muestra en la figura. Determine:

a) La intensidad del campo eléctrico en el punto medio P entre dos cargas puntuales

b) La fuerza sobre una carga q1 = -4 x 10-10 C colocada en el punto P

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
