q = - 5.70 × 10-9 nC
v = vxi + vyj + vzk
B = -1.30 T k
F = −( 3.10×10−7 N )i+( 7.60×10−7 N )j
Determining the Velocity of a Charged Particle
A particle with a charge of − 5.70 nC is moving in a uniform magnetic field of B =−( 1.30 T ) k̂. The magnetic force on the particle is measured to be F=−( 3.10×10−7 N ) î +( 7.60×10−7 N ) ĵ.
Calculate the scalar product v⋅F. Work the problem out symbolically first, then plug in numbers after you've simplified the symbolic expression.
Express your answer in watts to three significant figures.
