Statement I: If three forces F → 1 , F → 2 and F → 3 are represented by three sides of a triangle and F 1 → + F 2 → = - F → 3 , then these three forces are concurrent forces and satisfy the condition for equilibrium. Statement II: A triangle made up of three forces F 1 → , F 2 → and F 3 → as its sides were taken in the same order, satisfies the condition for trans
Options
- ABoth Statement I and Statement II are true.
- BStatement I is true but Statement II is false.
- CBoth Statement I and Statement II are false.
- DStatement I is false but Statement II is true.
Correct answer
A. Both Statement I and Statement II are true.
Step-by-step solution
Use triangle law of vector addition, here, F → 1 + F → 2 + F → 3 = 0 , since net force is zero it means the body is in equilibrium so both the statements are correct.
