A force Fmaking an angle e with the horizontal is acting on an object resting on the table. Which statement is true for the motion of sliding the
object on the table?
A.
It is independent of all the forces acting on the object.
OB.
It depends only on the forces acting along the x-axis.
О с.
It depends only on the forces acting along the y-axis.
OD
It depends only on the normal force acting on the object.
OE.
It depends only on the frictional force acting on the object.

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
