1.	In a conservation force field, a particle of mass 1 kg moving from rest from the origin. The potential energy at various x-coordinates as shown in graph. Findthe correct option if (du)/(dy)=(du)/(dz)=0
Answer» When the particle CROSSES -4m, the SPEED of the particle is `2sqrt(10)`m/sec When the particle crosses -4m, the speed of the particle is `2sqrt(20)` m/sec The particle is MOVING along +x-axis. The particle is moving along -x-axis. Answer :A::B::D
