Question

What will be the value of 1 gf
(A) 105 dyne
(B) 981 dyne
(C ) 9.8 N
(D) 1N

Answer 1

Hint: A gram- force, is a gravitational unit of force. That is one gram force is defined as the force exerted by one gram of mass in the standard value of gravitational field. The gram-force is equal to the product of mass of one gram by the standard acceleration due to gravity. Thus gram force is equal to 0.0098 Newton which is also equal to 980.665 dyne.

Complete step-by-step answer:
A gram- force, is a gravitational unit of force. That is one gram force is defined as the force exerted by one gram of mass in the standard value of gravitational field. Thus one gram force has a value equals to 9.8mN. The gram-force is equal to the product of mass of one gram by the standard acceleration due to gravity. Thus gram force is equal to 0.0098 Newton which is also equal to 980.665 dyne. Dyne is also a unit of force in centimeter gram second (CGS) units. One dyne is approximately equal to 0.00001 Newton.
Even though force has various units the S.I unit of force is Newton.

So, the correct answer is “Option B”.

Note: Thus one gram force has a value equals to 9.8mN. The gram-force is equal to the product of mass of one gram by the standard acceleration due to gravity. Thus gram force is equal to 0.0098 Newton which is also equal to 980.665 dyne. Dyne is also a unit of force in centimeter gram second (CGS) units. One dyne is approximately equal to 0.00001.
