In which direction does the electric field point at a position directly west of a negative charge?
Electric fields point in the direction of decreasing potential. If there is only one negative charge, the most negative spot would be directly where the charge is. If we measure the electric field to its west, the field would be pointing to the charge, which is to that point’s east.
What is the direction of the electric field at a point directly to the left of a positive charge?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
What is the direction of the electric field at the origin O?
The direction is away positive charge, and toward a negative one. At the origin, q1 will produce an E-field vector that points left, and q2 gives an E-field vector to the right.
In which direction does the magnetic field in the center of the coil point?
When the current flows through the solenoid in the clockwise direction, then the magnetic lines of force inside or at the center of the coil will be along the axis inwards according to right hand thumb rule.
How does the electric force between two charged particles change if the distance?
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value.
What is the magnitude of the electric field at a point 0.0050 m from a 0.0040 C charge?
Answers ( )
So, the magnitude of the electric field at 0.005m is 1.44 × 10¹² N/C.
