An electron falls through a distance 1.5 cm in a uniform electric field of magnitude 2.0 \(\times\) 10\(^4\) N/C from rest. The time taken to cover this distance in second is \textunderscore\textunderscore\textunderscore\textunderscore\textunderscore.
(e = 1.6 \(\times\) 10\(^{-19}\) C, m\(_e\) = 9.11 \(\times\) 10\(^{-31}\) kg)
A 200 J of work is done in moving a charge 5C from a point A where the potential is - 20 V to another point B where potential is V volt. The value of V at B is
An electric dipole of dipole moment \(\vec{P}\) is placed in the uniform electric field \(\vec{E}\). Then which of the following statements are correct?
Statement I: The torque on the dipole is \(\vec{P} \times \vec{E}\)
Statement II: The potential energy of the dipole is \(-\vec{P} \cdot \vec{E}\)
Statement III: The net force on the dipole is non zero
