What is Work done in moving a unit positive charge through a distance x on an equipotential surface?
No work is done in moving a unit positive charge through a distance x on an equipotential surface. This is because an equipotential surface has a constant electric potential, and work done is equal to the charge multiplied by the change in potential. Since the potential is constant, there is no change in potential and thus no work done.
What else can I help you with?
Q and -q are two charges d distances apartFind locus of a point at which electric fields are parallel to the line joining the charges?
Seems to me it has to be the line that passes through the mid-point of the line joining the charges, and perpendicular to it. It would be a line with slope = -1 / (slope of line joining the charges) and passing through the point that's (d/2) distant from both charges.
What The focal distance of a convex lens is always?
The focal distance of a convex lens is always positive. It is the distance between the lens and the focal point when light rays are parallel and converge after passing through the lens.
Applying a force through a distance known as?
Work is done when a force is applied through a distance. The amount of work done is calculated by multiplying the applied force by the distance over which it is applied. Work is a measure of energy transfer and can be positive or negative depending on the direction of the force relative to the direction of motion.
Does air resistance act at a distance?
Yes, air resistance acts on objects moving through the air at a distance. It is a force that opposes the motion of the object and is proportional to the object's speed and surface area facing the direction of motion.
If more electric field lines are leaving a gaussian surface than entering what can you conclude about the net charge enclosed by that surface?
If more electric field lines are leaving a Gaussian surface than entering, this indicates that there is a net positive charge enclosed by the surface. According to Gauss's Law, the total electric flux through a closed surface is directly proportional to the net charge enclosed by that surface.
What is the word for the distance through the center of a planet?
The distance from surface to surface through the center of a planet would be that planet's "diameter".
What is the distance through the earth's center from surface to surface?
7,000 km
Is equatorial circumference the same as radius?
No. The circumference is the distance around a circle or equaltor wheras the radius is the distance from the centre of a sphere (the centre of the earch if you will) to the surface. the diameter is twice the distance of the radius and is the distance from the surface of a sphere, through the middle point across to the other surface.
What is the purpose of equipotential bonding?
The purpose of equipotential bonding is to ensure that all conductive parts within an electrical installation or system are at the same electrical potential. This helps to reduce the risk of electric shock and prevent potential differences that could lead to dangerous currents flowing through unintended paths. Equipotential bonding also helps protect against lightning strikes and electromagnetic interference.

What is the build up of a positive or negative electric charge on a materials surface?
A positive or negative electric charge can build up on a material's surface through the gain or loss of electrons. This can occur through processes such as friction, induction, or conduction, where electrons are transferred between materials, resulting in an accumulation of charge.
What is a negative surface area?
This isnt factual but I think its a clever way to think of this. positive surface areas cause something to go around the object, no surface area (empty space) you could go right through, so by thinking along those lines you could go through space faster than your actual velocity by passing through a negative surface area.
