1J = 1Nm

Hope it may help you ☺☺

Answer 2

Another form of 1 Joule is a)1Nm.

• The SI unit of work done is Joule. However, mathematically, work done is the product of force and displacement which could be given as,

                            Work done = Force x displacement

                                                = F x S

• Since, the SI unit of Force is Newton and Meter for Displacement, the other SI unit of Force could be given as the product of the SI unit of Force and Displacement

• This could be given as the product of Newton and Meter which is Nm. Thus another form of 1 Joule is 1 Nm

• Therefore the correct option is a) Nm. Which could be given as Newton meter.
