Problem 1 (25 pts) - A balance is constructed from a nonconducting arm of length \"L\" (you can ignore the mass of the balance arm in this problem} The arm is balanced from its center. A mass \"M\" hangs at a distance \"a\" from the left end of the rod. 0n the left end of the rod a charge +q is attached and at the right end of the rod a charge +2q is attached. A distance "h" directly beneath each of these charges is a sphere of known charge +q. - A) Draw a freebody diagram of the balance with the charges and mass M and all forces labeled clearly (6 pts) * B) Find the distance \"a" the block will hang such that the rod is horizontal and balanced. (Assume the masses of the charges at the end of the rod is equal to zero) (9 pts) - B) With the block at the distance \"a" from part (A), what height "h" will result in the horizontal arm exerting no vertical force on the center of the balance (the triangle in the center of the figure below)?
