.Least count of a spring balance is 1 kgwt. per division. If the reading on this spring balance is 5 div, the force acting on it will be, (a) 5 N (b) 5 dyne (c) 5g N (d) 5g dyne why???

1 kgwt is basically 9.8N
so 5 divisions means (5 x 9.8) N
dyne is the unit of force in cgs system
so now rest of the question is self explainatory.
