Suppose a car is being driven forward by a force of 2600 N. The car also is dragging something by a rope which exerts a tension force of 400 N. If the car's
mass is 900 kg, what is the car's acceleration?

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.
