An object is accelerating is at the rate of ‘a1’ m/s2. If suddenly the net force exerted is doubled and the mass is quadrupled, find the new acceleration ‘a2’.

If a negatively charged particle is placed at rest in an electric potential field that increases in the positive x-direction, what will the particle do? a. accelerate in the positive x-direction b. remain at rest c. accelerate in the negative x-direction
