Mam agar hc ki value si unit me rakhte h to answer galat aa raha h

[@shradha_iitian]

if you are using SI unit of hc, then change all units to SI

Newton metre kya hai ...

[@abhatudu710]

Glt bola unhone it's nano meter ,1 nm= 10^-9 m

[@studypoint4115]

nm Newton metre hota hai maam ????

[@pablo-qv2jh]

nanometer
