How much work is required to turn an electric dipole 180° in a uniform electric field of magnitude E = 46.0 N/C if the dipole mo
chubhunter [2.5K]

Answer:

W=1.22*10^{-23}J

Explanation:

Torque and energy of an electric dipole in an electric field we find:

W=U(\alpha_{o}+\pi  )-U(\alpha_{o} )=-pE(cos(\alpha_{o}+\pi )-cos(\alpha_{o} ))\\W=2pECos\alpha_{o}\\ W=2(3.02*10^{-25}C.m )(46.oN/C)Cos64\\W=1.22*10^{-23}J

Gravitational Potential Energy of an object is calculated by formula ~

\large\boxed{\sf P = mgh}

where,

  • m = mass of the object = 3500 kg

  • g = Acceleration due to gravity = 12 m/s²

  • h = height attained by the object = 4 m

Now, let's calculate its potential energy ~

  • 3500 \times 10 \times 4
