Three point charges are located on a circular arc as shown in the figure. (a) What is the total
electric field at P, the center of the arc? (b) Find
the electric force that would be exerted on a
25.00-nC point charge placed at P.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

If gases like carbon dioxide and methane make up less than 1% of the total atmosphere, why is it important for scientists to monitor changes in percentages of these gases?
