Determine the magnitude and direction of the resultant of the following set of forces acting on a body (i) 200 N inclined 30° with east towards north,(ii) 250 N towards north, (iii) 300 N towards north west(iv) 350 N inclined at 40° with west toward south.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

What is the angular momentum of the bar about the axle?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
