Q1:

One Newton force, is

A 103 dynes

B 104 dynes

C 105 dynes

D 106 dynes

E 107 dynes.

ANS:C - 105 dynes

F=ma.

The unit of m and a is kg and m/s2 in MKS unit system;
Now convert it into a CGS unit system.
1kg= 1000g and 1m=100 cm and put in MKS unit system.
1 Kg m/s2=1 N= 1000g*100cm/s2= 10^5 g cm/s2=10^5 dynes. As: lbf = 4.448 N = 4.448 x 105 dynes. 1 lbf = 32.174 poundals = 32.174 Ibm ft/s2. 365.
