In a system, unit of mass is A ~kg , length is B ~m and time is C ~s , then the value of 10 ~N in this system is
Options
- A10 A⁻¹ B⁻¹ C⁻²
- B10 A⁻¹ B⁻¹ C^2
- C10 A B C⁻²
- D5 A⁻¹ B C^2
Correct answer
B. 10 A⁻¹ B⁻¹ C^2
Step-by-step solution
Using, (b) Using, aligned N₁ u₁ & =N₂ u₂ 10 ~kg m s ^2 & =N₂ ( A B C^2 ) N₂ & = 10 C^2 A B & =10 A⁻¹ B⁻¹ C^2 aligned So, numerical value of 10 ~N in given system is 10 A⁻¹ B⁻¹ C^2 .
