A particle has a mass of 6.0 $\times$ 10^-6 kg and a velocity of 800 m/s along the x axis when a force of 14.4 $\times$ 10^-5 N along the y axis acts on the particle at right angles to its velocity.The acceleration of the particle is A)24 m/s² along the x axis. B)zero. C)impossible to determine; forces never act at right angles to velocities. D)24 m/s² along the y axis. E)tangential.

The force is acting perpendicular to the velocity, so it will not change the velocity in the x direction. The acceleration will only be in the y direction, and can be found using Newton's second law: F = m*a. So, a = F/m = (14.4*10^-5)/(6.0*10^-6) = 2.4 m/s^2. The direction of this acceleration will be 90 degrees from the direction of the force, which is along the y axis. Therefore, the answer is D.
