Question
A vector $\overrightarrow{\text{A}}$ points vertically upward and $\overrightarrow{\text{B}}$ points towards north. The vector product $\overrightarrow{\text{A}}\times\overrightarrow{\text{B}}$ is:
  1. Along west.
  2. Along east.
  3. Zero.
  4. Vertically downward.
✓

Answer

  1. Along the west.
Explanation:
The vector product $\overrightarrow{\text{A}}\times\overrightarrow{\text{B}}$ will point towards the west. We can determine this direction using the right hand thumb rule.

A physicist works in a laboratory where the magnetic field is $2 T .$ She wears a necklace enclosing area $0.01 \mathrm{~m}^2$ in such a way that the plane of the necklace is normal to the field and is having a resistance $R=0.01 \Omega$. Because of power failure, the field decays to $1 T$ in time $10^{-3}$ seconds. Then what is the total heat produced in her necklace ? $(T=$Tesla$)$
