The angles of a triangle are in the ratio $3: 5: 10$. Then the ratio of the smallest side to the greatest side is:

An electric dipole of length $4 \ cm$ is placed with its axis making an angle of $30^{\circ}$ to a uniform electric field of $10^6 \ N/C$. If it experiences a torque of $20 \sqrt{3} \ Nm$,then the potential energy of the dipole is: (in $J$)
