Question

define electrical field mention its s i unit and dimensional formula

Answer 1

The space or region around a magnet or a current carrying conductor in which its influence can be felt by any magnetic substance.
The SI unit is tesla (T) 

Answer 2

===>The space or origin around a charge within which it's influence can be experience by another magnet is called electric field.

● its si unit is newton per meter .
Because E = F / q ...

●If the electric field strength is denoted by the symbol E, then the equation can be rewritten in symbolic form as

If the electric field strength is denoted by the symbol E, then the equation can be rewritten in symbolic form as
E = K. Q / D ^ 2
