B C D
This is not calculated, according to the analysis of the four options, the value of the four options into the verification on the line
To do this kind of multiple choice questions, press
The resultant force must be greater than or equal to the difference between the two components
The resultant force must be less than or equal to the sum of the two components
We can choose the answer quickly
Do you see the principle I wrote above, the value in a is two 10s, and their sum is only 20,
Is it consistent with the principle that the resultant force must be less than or equal to the sum of the two components?
