JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

Two points are at distances

\mathrm{a}

and

\mathrm{b}(\mathrm{a}<\mathrm{b})

from a long string of charge per unit length

\lambda

. The potential difference between the points is proportional to -

View answer and explanation

Correct option: D

\log (b / a)

Option A (332.5) is correct because it is the calculated speed of sound in air at standard temperature and pressure using the corrected Newton's formula, considering the mass of one mole of air and the adiabatic index.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance
