H) Field Intensity and Distance
 

 

1) Spherical point charge

 

 

 

Field intensity varies
inversely
 with the square of distance

 

 

 

Double distance from charge,

the field intensity ....

 

 

 

 

is quartered

 

 

 

2. Charged Rod - the field intensity varies inversely with distance

 

If the distance to the rod is reduced to 1/3 its original distance, the electric field intensity ...

 

 

 

would be 3 times greater
