A particle with charge -5.60 nC is moving in a uniform magnetic field βB=β(1.25T) k The magnetic force on the particle is measured to be βF=β(3.40Γ10β7N) ΛΔ± +(7.40Γ10β7N) ΛΘ·(a) Calculate all the components of the velocity of the particle that you can from this information. (b) Are there components of the velocity that are not determined by the measurement of the force? Explain. (c) Calculate the scalar product βv β βF . What is the angle between βv and βF

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries β2.50 pc of charge and the other β3.10 pc, and each cell can be modeled as a sphere 7.5 ΞΌm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer
