JEE Main2012PhysicsElectrostaticsActual
This question has statement 1 and statement 2 . Of the four choices given after the statements, choose the one that best describes the two statements. An insulating solid sphere of radius R has a uniformly positive charge density . As a result of this uniform charge distribution there is a finite value of electric potential at the centre of the sphere, at the surface of the sphere and also at a point out side the sph
Options
- AStatement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation for statement 1 .
- BStatement 1 is true, Statement 2 is false
- CStatement 1 is false, Statement 2 is true
- DStatement 1 is true, Statement 2 is the correct explanation for statement 1
Correct answer
C. Statement 1 is false, Statement 2 is true
Step-by-step solution
E d A = 1 ₀ ( 4 3 r ^3 ) E = r 3 ₀ Statement 2 is correct PE = ( V _ sur - V _ cent ) q =- q 6 ₀ R ^2 Statement 1 is incorrect
