Two forces, 1 N and 2 N, act along with the lines x = 0 and y = 0. The equation of the line along which the resultant lies is given by:
1. y - 2x = 0
2. 2y - x = 0
3. y + x = 0
4. y - x = 0
Component of perpendicular to and in the same plane as that of is:
Given that makes an angle . Which of the following options is correct?
If the angle between the vector is , the value of the product is equal to:
Two forces A and B have a resultant . If B is doubled, the new resultant is perpendicular to A. Then
Assertion: The graph between P and Q is a straight line when P/Q is constant.
Reason: The straight-line graph means that P is proportional to Q or P is equal to a constant multiplied by Q.
Which one, of the following statements, is correct?
1. If both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
2. If both the assertion and the reason are true but the reason is not the correct explanation of the assertion.
3. If the assertion is true but the reason is false.
4. If the assertion and reason are both false
Two forces of magnitude F have a resultant of the same magnitude F. The angle between the two forces is
Two forces with equal magnitudes F act on a body and the magnitude of the resultant force is F/3. The angle between the two forces is
Two forces are such that the sum of their magnitudes is 18 N and their resultant is perpendicular to the smaller force and the magnitude of the resultant is 12 N. Then the magnitudes of the forces will be:
1. 12 N, 6 N
2. 13 N, 5N
3. 10 N, 8 N
4. 16 N, 2 N
If two forces of 5 N each are acting along X and Y axes, then the magnitude and direction of resultant is
