Answer:d
Explanation:
Given
Magnitude of Vector A is 3 m
and Magnitude of vector B is 4 m
So the maximum value of resultant can be 7 m when both are at an angle of
and its minimum value can be 1 m when both are at angle of
So the resultant must lie between 1 m to 7 m
They should be bigger as if it is hot the tracks will expand as it is made of metal and then there is more room for it to expand or contract
