A force of 6 kg and another of 8 kg can be applied together to produce the effect of single force of-
(C) 15 kg
(D) 20 kg
Need proper explanation
First, consider 6 and 8 at 180degree that is opposite directions.
Now, the result would be a force of 2.
Consider the same thing in the same direction i.e. 0degree and the result will be 14.
So, at any angles between 0degree and 180degree, the output will be between 2 and 14.
By considering all these things, the result will be 11.
Hope it's Helpful for you....
