Relation between SI unit and CGS unit of force
1 dyne = 105N
1 N =10-5 dyne
1 dyne =9.8N
1 N = 105 dyne
The correct option is A. 1 N = 105 dyne
1N = 1 kg x ms-2 = 1000g x 100 cms-2 = 105g cms-2 =105 dyne.
Young's modulus of steel is 19×1010Nm2. Express it in dynecm2. Here dyne is the CGS unit of force.
