Addition of which of the following will not be equal to zero - a) 10,10,10 b)10,10,20 c) 10,20 ,30 d) 10,20,40
Answers
Answer:
d) 10,20,40
Explanation:
The conditions in which the resultant of forces may become zero will be
- If the forces form a triangle, then by using the triangle law the forces may become zero according to their directional orientation. For example a) 10,10,10 or b) 10,10,20
- The resultant forces may also become zero if the total sum of forces in one direction is exactly opposed by the force of the same magnitude that is in the opposite direction. For example 10+10 in one direction and 20 in opposite direction.
Thus, if the magnitude of any vector is more than the sum of the other remaining two vectors, then the resultant cannot be zero. Thus, in the case of option d) as 40>20 + 10.
Therefore, the only set of forces which will neither form a triangle or which would not have equal amount of forces in opposite direction is option D) 10,20,40
