Question1

An electron is a subatomic particle (m = 9.11 × 10^-31 kg) that is question to electric forces. An electron moving in the +x direction accelerates from an original velocity of +5.40 × 10^5 m/s to a final velocity of +2.10 × 10^6 m/s whereas travelling a distance of 0.038 m. The electron's acceleration is due to two electric forces parallel to the x axis: and, that points in the -x direction. Find out the magnitudes of

(a) Net force acting on the electron and

(b) Electric force.

Question2

An unknown force pushes a 17 kilogram block across a smooth (frictionless) floor. Three seconds after the force is first applied to block, the block is moving with a speed of 6 meters per second. What is magnitude of the unknown force?
