Question

and electric the float held act on angry of 30 degree with respect to inform electric field of 4 into 10 ki power 4 Newton per coulomb experiences a triangle of 1.618 into 10 ki power 25 Newton metre

Answer 1

It is actually an electric dipole. It is mistyped...   Not angry .. it is angle.

Let the distance between the charges q and -q in the dipole, be 2a.
Ф = angle between electric field E and dipole. = 30°.
E = 4 * 10⁴ N/C
F = force on each charge = q E
Torque = 1.6 * 10⁻²⁵ Nm
Dipole moment = P = 2 a q

Torque on dipole = 2 | r X F | = 2 a F SinФ 
          =  2 a q E sinФ 
          = P E sinФ
   1.6 *10⁻²⁵ = P * 4 * 10⁴ * sin30°

   P = 8 * 10⁻³⁰ Coul-meter

Answer 2

Let the distance between the charges q and -q in the dipole,

be 2a.Ф = angle between electric field E

and dipole. = 30°.E

= 4 * 10⁴ N/CF

= force on each charge

= q ETorque

= 1.6 * 10⁻²⁵ NmDipole moment

= P

= 2 a qTorque on dipole

= 2 | r X F |

= 2 a F SinФ        

 =  2 a q E sinФ          '

= P E sinФ   1.6 *10⁻²⁵

= P * 4 * 10⁴ * sin30°   P

= 8 * 10⁻³⁰ Coul-meter
