Question

Out of the following set of forces, the resultant of which cannot be zero? 10, 10, 10 O 10, 10, 20 20, 20, 10 O 10,20,35​

Answer 1

Explanation:  

We know that,

In the triangle, addition of the two sides is greater than the third side then the resultant might be zero but when addition of the two sides is less than the third side then the resultant can not zero.

The resultant force is zero.

a = 10, b = 20, c = 40

The resultant force is

$(a + b) < c \\(30) < 40$

The resultant force is not zero. The answer is 10, 20, 40
