A proton moving in a uniform magnetic field with v⃗ 1=1.16×106ı^m/s experiences force F⃗ 1=1.61×10−16k^N. A second proton with v⃗ 2=2.26×106ȷ^m/s experiences F⃗ 2=−3.86×10−16k^N in the same field. A. What is the magnitude of B⃗ ?B. What is the direction of B⃗ ? Give your answer as an angle measured ccw from the +x-axis

Una carga puntual de 3 x 10-6 c se coloca a 12 cm de una segunda carga puntual de - 1,5 x 10-6 c. calcular la magnitud fuerza eléctrica entre las cargas

Aball is thrown horizontally from a cliff at 8m/s .in what direction is the ball moving 2s later?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
