Question

At one instant an electron is moving in the xy plane, the components of its velocity being $v_x = 5 imes 10^5$ m/s and $v_y = 3 imes 10^5$ m/s. A magnetic field of 0.8T is in the positive x-direction. At that instant the magnitude of the magnetic force on the electron is: $2.6 imes 10^{-14}$ N $1.0 imes 10^{-13}$ N $6.4 imes 10^{-14}$ N $3.8 imes 10^{-14}$ N

          At one instant an electron is moving in the xy plane, the components of its velocity being $v_x = 5 	imes 10^5$ m/s and $v_y = 3 	imes 10^5$ m/s. A magnetic field of 0.8T is in the positive x-direction. At that instant the magnitude of the magnetic force on the electron is:

$2.6 	imes 10^{-14}$ N
$1.0 	imes 10^{-13}$ N
$6.4 	imes 10^{-14}$ N
$3.8 	imes 10^{-14}$ N

At one instant an electron is moving in the xy plane; the components of its velocity being vx = 5 x 10^5 m/s and vy = 3 x 10^5 m/s. A magnetic field of 0.8T is in the positive x-direction. At that instant the magnitude of the magnetic force on the electron is: 2.6 x 10^-14 N 1.0 x 10^-13 N 6.4 x 10^-14 N 3.8 x 10^-14 N
