How can you experimentally distinguish an electric field from a gravitational field?
Introduce two opposite charged objects one AT A TIME and if they move IN THE SAME DIRECTION, they are in a gravitational field, if they move IN DIFFERENT direction they are in an electric field.
Electric field lines point in the opposite direction charges would move if they were in the field?
positive
If you place a charge into an electric field it will move in the direction indicated by the electric field lines?
it will occure if the charge is positive, other wise it will move to opposite direction.
What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
When the negatively charged object moves in the opposite direction of an electric field the potential energy of the object?
decreases

Relationship between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.

The direction of the electric field vector is defined as?
Direction of the electric field vector is the direction of the force experienced by a charged particle in an external electric field.
When the negatively charged object moves in the opposite direction of an electric field the potential energy of the object?
decreases
How can you show that something is electrically charged?
Pass it through an electric field, if it changes direction then it is charged.
How can the electrical potential energy of a charged particle in an electric field be increased?
THIS IS A GOOD QUESTION IF WE PLACE THE CHARGE IN THE ELECTRIC FIELD AT A DISTANCE R FROM THE ELECTRIC FIELD AND PLACED THE ANOTHER POINT CHARGE AT A ANOTHER DISTANCE r WHERE R IS GRATER THAN THE SMALL R THEN THE ELECTRIC FIELD AT r IS MORE THAN THE ELECTRIC FIELD AT POINT R.ORWE CAN SAY THAT IF THE CHARGE IS PLACED IN THE DIRECTION OF ELECTRIC FIELD THAN ITS ELECTROSTATIC POTENTIAL ENERGY WILL DECREASE OR WHEN IN DIRECTION OPPOSITE THAN VICEVERSA
Is the direction of the electric force on a charge is tangent to the field line?
yes,the direction of electric force on a charge is tangent of field lines.
What is the direction of electric field?
This question is impossible to answer because the force is dependant on the strength of the electric field. This will depend on how many other charges there are and how far away. The strength of an electric field is proportional to the number of charges and the inverse square of the distance. Strength of field = C x N / D2 where C is some constant, N is the number of charges (-ve will repel +ve will attract for and electron) and D is the distance between the electron and the charges creating the field.
When determining an electric field must a positive test charge be used or would a negative one do as well?
We could just as well use a negative test charge to determine an electric field, but then the Electric field vector would point opposite the direction of the force on the test charge.
