Question

76. Mark the correct statement 1. If velocity and acceleration have opposite sign, then speed of particle will increase 2. If velocity is zero at an instant then acceleration of particle will be zero at that instant 3. If the velocity is zero in a time interval then acceleration is not equal to zero at any instant within the time interval 4. A particle can move along X axis only. If it's X coordinate and velocity has opposite sign then particle will move towards origin
