Question

An electric field is given by ( 6 i ^ + 5 j ^ + 3 k ^ ) N C - 1 . The electric flux through a surface area 30 i ^ m 2 lying in YZ-plane(in SI unit) is:, 90, 150, 180, 60

MARKS App · Accepted Answer

Given: E → = ( 6 i ^ + 5 j ^ + 3 k ^ ) N C - 1 A → = 30 i ^ m 2 ϕ = E → · A → ⇒ ϕ = ( 6 i ^ + 5 j ^ + 3 k ^ ) · ( 30 i ^ ) = 180 SI unit
