An electron that has a velocity with x component 1.9 x106 m/s and y component 4.2 x 106m/s moves through a uniform magnetic field with xcomponent 0.025 T and y component -0.17 T.(a) Find the magnitude of the magnetic force on the electron. (b) Repeat your calculation for aproton having the same velocity.
In the figure, block 1 of mass m1 slides from rest along a frictionless ramp from height h = 2.1 m and then collides with stationary block 2, which has mass m2 = 5m1. After the collision, block 2 slides into a region where the coefficient of kinetic ..
