## Ruchi. 3 years ago 4 force of magnitude P,2P,3P,4P ACt along the four side of a square ABCD in cyclic order.use the vector method to find the resultant force.

|dw:1337765285728:dw|

2. Sandy730

4P is the resultant according to the polygon law of forces but it should be in opposite direction.

3. Ruchi.

use vector method

4. Sandy730

I think polygon law is based on Vector only.

5. Ruchi.

yes

6. chand

alright. vectors can be slid in a direction parallel to theirs. So, it would become |dw:1337765692337:dw|

7. chand

are you clear so far?

8. Ruchi.

no more confuse.

9. chand

more confused?

10. Sandy730

Any solution pls let me know too...

11. Sandy730

@ chand ...What about resultant ...That will be one..

12. X32

just what shayanreloaded drew. but if P is a variable and P-3P=-2P horizontal, 2P-4P=-2 vertical

|dw:1337800454038:dw| corrected!

@Ruchi. di, ab samajh mein aaya na?

15. **AJ**

answer is 2p * underroot 2|dw:1337954498341:dw|

16. **AJ**

adarsh i think ur solution is little bit critical... itzz so easy yarr

17. Shruti237

Hi all....pls tell me why cant the resultant be simply zero..since when vectors are represented by the sides of a closed polygon taken in same order, the resultant is zero. Pls help!!!!
