Question

10.A Charged sphere of radius 1m carries a charge of 1 x 10-9 C. The electric fields at a point P, which is at a distance d = 3m from the centre of the sphere and at a point Q, at a distance d = 0.3m from the centre of the sphere are respectively

Answer 1

Answer:

1  ,  100

Explanation:

F=k q/r2

from the center of the sphere..

Answer 2

Answer:

1 N/C

Explanation:

• Here, we must determine the electric fields at d=3 and d=0.3 metres.
• Given
• One metre in diameter and carrying a charge (Q)=1 x 10-9 C
• d=3m at a distance:
• $*e=kg/r^2\\k=1/(4pi)e = 9*10^9\\electric field=9*10^9*10^{-9}/3*3\\=1$
• the electric field is 1N/c at a distance of 3m.
• Distance d=0.3 metres:
• $e=kg/r^2\\=9*10^9*10^-9/0.3*0.3=100$
• 100N/c electric field at a distance of 0.3 m
• Each location in space where a charge exists in any form can be considered to have an electric field attached to it. The electric force per unit charge is another name for an electric field.
• The electric field's formula is as follows:
• E = F /Q
• Where,
• Electric field symbol: E.
• Force F exists.
• The charge is Q.
