##### Reference no: EM1365127

Q. A very small charged block with a mass of 2.05 g is placed on an insulated, frictionless plane inclined at an angle of 17.0° with respect to the horizontal. The block does not slide down the plane because of a 490 N/C uniform electric field that points parallel to the surface downward along the plane. What is the charge on the block?

Q. A car traveling 99km/h is 140m behind a truck traveling 72km/h. How long will it take the car to reach the truck?
