How many Dynes are there in one gram weight?
C
Correct answer
Explanation
One gram weight is the force exerted by one gram mass under standard gravity (g=9.81 m/s²). In the CGS system, 1 dyne = 1 g·cm/s². Using F=ma and converting units: 1 gram weight = 1 gram × 981 cm/s² = 981 dynes. This is a standard conversion factor used in mechanics.
