Question

Let there be a spherically symmetric charge distribution with charge density varying as `rho("r") = rho_0(5/4 - "r"/"R")` upto r = R, and `rho("r") = 0` for r > R, where r is the distance from the origin. The electric field at a distance r(r < R) from the origin is given by _________.

विकल्प

• `(rho_0"r")/(4epsilon_0) (5/3 - "r"/"R")`

• `(4pirho_0"r")/(3epsilon_0) (5/3 - "r"/"R")`

• `(4rho_0"r")/(4epsilon_0) (5/4 - "r"/"R")`

• `(rho_0"r")/(3epsilon_0) (5/4 - "r"/"R")`

Answer 1

Let there be a spherically symmetric charge distribution with charge density varying as `rho("r") = rho_0(5/4 - "r"/"R")` upto r = R, and `rho("r") = 0` for r > R, where r is the distance from the origin. The electric field at a distance r(r < R) from the origin is given by `underline((rho_0"r")/(4epsilon_0) (5/3 - "r"/"R"))`.
