A body, under the action of a force F =6 i -8 j +10 k , acquires an acceleration of 1 ms ⁻² . The mass of this body must be
Options
- A2 10 ~kg
- B10 ~kg
- C20 ~kg
- D10 2 ~kg
Correct answer
D. 10 2 ~kg
Step-by-step solution
Key Idea According to Newton's second law of motion, force = mass acceleration. Here, Here, aligned F & =6 i -8 j +10 k | F | & = 36+64+100 & =10 2 ~N a & =1 ~ms ⁻² m & = 10 2 1 =10 2 ~kg aligned
