Which of the following is equivalent to tesla ?
aAmpere per Newton
bNewton per Coulomb
cNewton per ampere-second
dNewton per ampere metre✓ Correct
Explanation
Tesla (T) is the SI unit of magnetic flux density. Magnetic flux density is a measure of the magnetic field. Among the given options, Newton/(Ampere-metre) is equivalent to tesla. $$ tesla = \frac{wb}{m^2} = \frac{N}{Amp.m} $$ $$ = \frac{volt.sec}{m^2} $$
