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 sphere. The electric potential at infinity is zero.
Statement 1 : When a charge q is taken from the centre to the surface of the sphere, its potential energy changes by
Statement 2 : The electric field at a distance r(r < R) from the centre of the sphere is
Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation for statement 1.
Statement 1 is true, Statement 2 is false
Statement 1 is false, Statement 2 is true
Statement 1 is true, Statement 2 is the correct explanation for statement 1
As we discussed in
If P lies at centre r = 0 -
i.e
-
Potential at the centre of the sphere,
Potential at the surface of the sphere,
When a charge q is taken from the centre to the surface, the change in potential energy is
Statement 1 is false. Statement 2 is true.
Option 1)
Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation for statement 1.
Option 2)
Statement 1 is true, Statement 2 is false
Option 3)
Statement 1 is false, Statement 2 is true
Option 4)
Statement 1 is true, Statement 2 is the correct explanation for statement 1
