  In space, the electric potential varies as $V = 20|r|$ volt, where $\vec{r} = x\hat{i} + y\hat{j} + z\hat{k}$ is the position vector. Then electric field in (N/C) at the point (4 m, 3 m, -5 m) is

  • $-\sqrt{2} (4i + 3j - 10k)$
  • $-\sqrt{2} (8i + 6j - 10k)$
  • $-(8i + 6j - 10k)$
  • $4i + 3j - 5k$

Block A is displaced towards block B by 2 m and block C is displaced towards block B by 3 m. The distance through which the block B should be moved so that the centre of mass of the system does not change is

  

  • 1.4 m, towards block C
  • 1.5 m, towards block A
