an electron travels at a horizontal velocity of 5×10^6m/s in vacuum between two charged plates 100mm long and 20mm apart, towhich potential difference of 30v is applied. the chargeon an electron is 1.5×10^-19c and the mass of an electron is 9.1×10^_31kg. what size force will the electron experience while it passes through the plates?​

If the work required to stretch a spring 3 ft beyond its natural length is 15 ft-lb, how much work is needed to stretch it 27 in. beyond its natural length?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
