Sr. # Questions Answers Choice
1 The velocity of a particle at an instant is 10 m/s and after 5s the velocity of the particle is 20 m/s. The velocity 3s before in m/s is: 8 4 6 7
2 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<b style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 16px;">°</b> Perpendicular to each other
3 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
4 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
5 Two forces of 10N and 15N are acting simultaneously on an object in the same direction. Their resultant is Zero 5N 25N 150N
6 Two forces are acting together on an object. The magnitude of their resultant is minimum when the angle between the force is 0<b style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 16px;">°</b> 60<b style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 16px;">°</b> 120<b style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 16px;">°</b> 180<b style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 16px;">°</b>
7 A force of 10N is acting along y-axis. Its component along x-axis is 10N 20N 100N Zero N
