A body, under the action of a force F =6 i -8 j +10 k , acquires an acceleration of 1 ~m / s ^2 . The mass of this body must be :
Options
- A10 2 ~kg
- B2 10 ~kg
- C10 ~kg
- D20 ~kg
Correct answer
A. 10 2 ~kg
Step-by-step solution
aligned F & =6 i -8 j +10 k | F | & = 6^2+8^2+10^2 =10 2 ~m & = | F | a = 10 2 1 =10 2 ~kg aligned
