An electric dipole of moment overset(r )...

An electric dipole of moment `overset(r )( P) = (hat( i) + 3 hat(j) -5 hat(k ) ) xx 10^(-19 ) Cm` is kept in a electric field `overset( r )( E ) = = ( 2hat( i) - 3 hat( j )+2 hat( k) ) xx 10^(5) V- m`. Find torque experienced by dipole.

A

`( 9 hat( i )+ 12 hat(j ) -9 hat(k)) xx 10^(-14) N -m `

B
