Sr. # Questions Answers Choice
1 The sum of the magnitude of two forces acting at a point is 18 and the magnitude of their resultant is 12. If the resultant is at 90° with the force of the smaller magnitude then their magnitude are: 3, 15 4, 14 5, 13 6, 12
2 A motorist travels A to B at a speed at 40 km/h and returns at speed of 60 km/h. His average speed will be: 40 km/h 48 km/h 50 km/h 60 km/h
3 The velocity of a particle at an instant is 10 m/s and after 5 s the velocity of the particle is 20 m/s.The velocity 3s before in m/s is: 8 4 6 7
4 To get a resultant displacement of 10 m, two displacement vectors of magnitude 6 m and 8 m should be combined Parallel Antiparallel At angle 60° Perpendicular to each other
5 The dot product of two vectors is negative when They are parallel vectors They are anti-parallel vectors They are perpendicular vectors None of the above is correct
6 If two non-zero vector ̅A̅ and ̅B are parallel to each other, then ̅A̅, ̅B is equal to Zero AB A + B A - B
7 If the dot product of two non-zero vectors vanishes the vectors will be In the same direction Opposite to each other Perpendicular to each other Zero
8 Two forces of 10N and 15N are acting simultaneously on an object in the same direction. Their resultant is Zero 5N 25N 150N
9 Two forces are acting together on an object. The magnitude of their resultant is minimum when the angle between the force is. 60° 120° 180°
10 A force of 10N is acting along y-axis its component along x-axis is 10N 20N 100N Zero N
