A Particle Has a Mass of 6 $\times$ 10^-6 Kg and a Velocity of 800 M/s Along the and a Velocity

Multiple Choice

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.
