Two metal plates 4 cm long are held horizontally 3 cm apart in a vacuum, one being vertically above other. The upper plate is at a potential of 3000 & the lower is earthed. Electrons having a velocity of 1×10^7 m/s are injected horizontally midway between the plates & in the direction parallel to 4 cm edge. Calculate the vertical deflection of the electron beams as it emerges from the plates. (Assume “e/m=1.8×10^11 c/kg”).

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
