A camper is trying to move a rock by creating a lever out of a wood board and another rock. Using the
second rock as a fulcrum, he places it 1.50 m from the point at which he will exert a force. How much torque
will he exert if he applies a force of 200 N: (2 pts)
a) perpendicular to the board?

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
