name the physical quantity whose SI unit is VOLT PER METRE . is it a scalar or vector quantity?
The SI unit of potential gradient is volt metre-1 (Vm-1).
Potential gradient is defined as the change in potential with respect to distance.
dV/dx,dV/dy,dV/dz represents potential gradient distance w.r.t x axis,y axis and z axis respectively.It is a scalar quantity.
