SI unit of tension is N/m, we have to write its dimensions in terms of [EVT], which is [(Nm), (m/s), (s)]. Hence we can write N/m in terms of EVT as [E^a V^b T^c] where a,b and c are some variables. We put the the SI expansions for EVT as [(Nm)^a (m/s)^b (s)^c]and write equations in a,b and c to get N/m as a=1, a+b= (-1) and (-b)+c=0 to give a= 1, b= (-2) and c= (-2). Hence [T] = [E V^-2 T^-2]
