d. all of these
look at the picture to know from where we get this law with application on it
Answer: Reflected
Explanation: Color Gradient refers to the variety of position dependent (as the vary with position) colors which are used to fill a region. Gradient is a mixture of two or more colors. This blend of colors adds depth to the design.
Types of color gradient are
- Linear: The color blends in a straight from starting to ending point
- Radial: The color transitions from starting point to ending a circular pattern.
- Angle: It glides counterclockwise around starting point.
- Diamond: It makes a diamond shape from starting point and its ending point is one corner of diamond.
- Reflected: In this color gradient type symmetric linear gradient gets mirrored on either side of the starting point. This type of color gradient can be used to depict a lead pipe.
"The potential on the surface of a conductor is always zero."
This statement is false. A good number of times we define a point's potential to be the amount of work that must be done to move 1 coulomb of charge from infinitely far away to that point. So if, let's say, the conductor had a net positive charge, then you would need to do a net positive amount of work to move 1 coulomb of charge from infinitely far away to any point on the conductor's surface. We have just provided a case for which the potential on the surface of the conductor is not 0.
