Question

Problem 7. In C.G.S system the magnitude of the force is 100 dynes. In another system where the fundamental physical quantities are kilogram, metre and minute, the magnitude of the force is
(a) 0.036 (b) 0.36 (c) 3.6 (d) 36

Answer 1

1 Dyne = One gram of mass moved with an acceleration of 1 cm per second squared.

1 Dyne = 0.00001 Newtons
that is,
1 Dyne = 10 raised to power -5

To change dynes to Newtons,
we have to multiply dynes with 10 raise to power -5.

100 dynes = 100×0.00001 Newtons.
100 dynes = 0.001 Newtons.
