A 1020 kg artillery shell is fired from a battleship. While it is in the barrel of the gun, it experiences an acceleration of 2.3 × 104 m/s2. 1. What net force is exerted on the artillery shell before it leaves the barrel of the gun (in Newtons)?
2. What is the magnitude of the force exerted on the ship by the artillery shell in Newtons?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
