Question

A long, straight wire lies along the $x$-axis and carries current $I = 50.0$ A in the $+z$-direction. A small particle with mass $3.00 \times 10^{-6}$ kg and charge $8.00 \times 10^{-3}$ C is traveling in the vicinity of the wire. At an instant when the particle is on the $y$-axis at $y = 9.00$ cm, its acceleration has components $a_x = -5.00 \times 10^3$ m/s$^2$ and $a_y = +9.00 \times 10^3$ m/s$^2$. Part A At that instant what are the $x$- and $y$-components of the velocity of the particle? Express your answer in kilometers per second. Enter your answers numerically separated by a comma. $v_x, v_y = 0.304, -0.169$ km/s

A long, straight wire lies along the Z-axis and carries current I = 50.0 A in the +z-direction. A small particle with mass 3.00 x 10 kg and charge 8.00 x 10 C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 9.00 cm, its acceleration has components a_x = -5.00 x 10^3 m/s² and a_y = +9.00 x 10^3 m/s².
