Two stationary point charges of +60.0 uC and +50.0 uC exert a repulsive force on each other of 175 N. What is the distance between the two charges?

The value is

Explanation:

From the question we are told that

     The first point charge is

      The second point charge is  

     The repulsive force exerted is  

Generally the repulsive force  exerted is mathematically represented as

Here k is the coulomb constant with a value  

So

=>    

=>

step-by-step explanation:

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
