Name these charges

 

 

A is negative B is positive

 

 

 

 

 

H) Field Intensity and Distance
 

 

1) Spherical point charge

 

 

 

Field intensity varies
inversely
 with the square of distance

Double distance from spherical 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
