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:

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

4. A 20 N force pushes a cart. That cart accelerates at a rate of 10 m/s/s. What will the acceleration of the

SpyIntel [72]

F=ma
=> 20=10m so m=2
Then the force is doubled 20.2=40
F'=ma'
m does not change so 40=2.a'
a'=20 which is option b.
