Consider a particle with positive charge q = 8.00 * 10^18 C moves with velocity v=(4i + 2j - k) m/s through a region where both a uniform electric field and a uniform magnetic field exist. calculate the total force on the moving particle, where B = (4i + 3j + k) T and E = (2i - j - 3k) V/m. Express the answer in component form.
A mechanic pushes a 2.20 x10^3 kg car from rest to a speed of v, doing 5400 J of work in the process. During this time, the car moves 28.0 m. Neglecting friction between car and road, find each of the following.
A mass of 125g is suspended from a spring of a spring constant of 38N/m. When this mass is pulled down 3mm and set in oscillation, what is the period and frequency of the oscillation? How different would be both, the period and frequency, if the m..
