(a)
To Find:The angle between the two forces
(a)
Answer to Problem 115E
If the magnitude of the resultant is equal to the sum of the magnitudes of the forces, then the angle between the forces is
Explanation of Solution
Given information:
Two forces of equal magnitude acting on a point
Concept used: let
and
be
Calculation:
If the magnitude of the resultant is equal to the sum of the magnitudes of the forces, then the angle between the forces is 0°
(b)
To Find:If the resultant of the forces is
(b)
Answer to Problem 115E
Resultant of the forces is equal to zero when the angle between the forces is
Explanation of Solution
Given information:
The resultant of the forces is
Concept used: let
and
be vectors. Then the sum of u and v is the vector
Calculation:
If the resultant of the forces is
Resultant of the forces is equal to zero when the angle between the forces is
(c)
The magnitude of the resultant be greater than the sum of the magnitudes of the two forces
(c)
Answer to Problem 115E
the magnitude of the resultant cannot be greater than the sum of the magnitudes of the two forces
Explanation of Solution
Given information:
Two forces of equal magnitude acting on a point
Concept used: let
And
Calculation:
The magnitude of the resultant is equal to the sum of the magnitudes of the forces, when the angle between the forces is
Therefore, the magnitude of the resultant cannot be greater than the sum of the magnitudes of the two forces
