Two point charges plus q and -q are held some distance apart what are the points at which the resultant field is parallel to the line joining the two charges?
The system of two point charges plus q and -q constitutes an electric dipole.In the case of an electric dipole ,the resultant field is parallel to the line joining the two charges at 1.any point on the line joining the charges 2.any point on the perpendicular bisector of the line joining the two charges.
Which term is used to describe objects are visible because of reflected light?
illuminatedThats the right answer for a plus.
In what way are magnetic poles very different from electric charges?
Magnetic poles can not exist and monopoles but must be in pairs where you have a force from one polarity to another. Electric charges, such as plus and minus, can exist alone.
A charge of plus Q attracts a charge of -Q 1 cm away with a force of F Another charge of plus Q is placed next to the first one The force on the charge of -Q is now?
If these are point charges each will apply a force F, so I guess the answer is 2F. If they are charges of finite physical size then the force from each won't be in line, so the result will be less.
A point charge plus Q1 exerts electrostatic force on point charge plus Q2 that is 3 cm away if charges are now 6 cm apart what force will Q1 exert on Q2?
Just like the gravitational force between masses, the electrostatic force between two charges is inversely proportional to the square of the distance between them. When the distance between the charges is changed from 3cm to 6cm, the distance changes by the factor of (6/3) = 2. The force changes by the factor of ( 1/22 ) = 1/4. Its magnitude changes to 0.25 that of the original force.
What are entities in c plus plus?
Entities are the objects instantiated by your program, both at compile time and at runtime. Some objects are primitive data types, others are more complex such as objects instantiated from a class.
What does the symbol Al3 plus tell you?
AL has 3 more negative charges than positive ones
What do you mean by read only objects in c plus plus?
Objects that are not supposed to be written. Surprised?
Why isn't two plus two five?
To get to five, there must be more than two objects. However, there are only two objects being added to two other objects. That answer is four, not five.
How do you call 2 or more objects in c plus plus?
It's not clear what you mean by "call 2 or more objects". Object's aren't "called", they are instantiated. Once instantiated you may "call" (invoke) the member methods associated with those objects, or invoke functions that operate upon those objects. To invoke the same member method on 2 or more objects, simply place those objects in a vector (by reference), then iterate over the vector: void f (std::vector<my_object*> objects) { for (auto foo : objects) foo->bar(); // invoke the bar method for each foo object in objects }
What are the objects used in dev c plus plus?
Objects in Dev C++ are the same as objects in generic C++, insofar as an object is an instance of a class.
Instantiation of objects in c plus plus?
Objects are instantiated when statically declared or dynamically created with the new keyword.
What is the difference between active and passive objects in c plus plus?
Passive objects encapsulate state and operations, whereas active objects also encapsulate a process. Standard C++ does not support active objects.
How do you spell heavy plus er?
The comparative of heavy is "heavier" (having more weight).
What determins an objects thermal energy?
What determines an objects temperature. The higher the temperature the faster the particles move, the more Kinetic Energy they have and the greater the objects Thermal energy=) Haha I am superr dupper dumb
How many plus charges dose this atom have?
about 3 or 4
Who invented the designation of plus and negative charges?
alex oulton
