Sapling Learning of the following situations. Determine the drection of the force (rany)that act on the charge in each A positive charge within an electric feld that points upward. A negative charge within an electric field that points to the left. moving into the soreen in a A positive to the right. magnetic field that points A negative maing upward in a magnetic charge points out of the screen. field that A positive charge moving to the left in an electric field that points into the screen. A negative charge moving upward in a magnetic field that points upward. ward into the screen the lout of the scree o Previous Give Up & View Solution check Answer 0Ned Hint

Explanation / Answer

(a) for a positive charge, the direction of force is same as the direction of eletric field.so the force will be upwards.

(b)for a negative charge, the direction of force is in the opposite direction of eletric field.so the force will be towards right.

(c) the direction on the charged particle in a magnetic field is given by right hand cross product rule; so direction of force is downwards.

(d)using right hand cross product rule, the force is towards left.

(e)for a positive charge, the direction of force is same as the direction of eletric field.so the force will be into the screen.

(f) there will be no force on negative charge in this case as the angle between velocity and magnetic field =0

so f= q v b sin0 =0
