A small piece of dust of mass m = 2.0 µg travels through an electric air cleaner in which the electric field is 549 N/C. The electric force on the dust particle is equal to the weight of the particle. What is the charge on the dust particle? If this charge is provided by an excess of electrons, how many electrons does that correspond to?
The spring constant of a toy dart gun is 5000 N/ M. To cock the gun the spring is compressed 3 cm. Estimate the speed of the projectile when it returns to its starting point
