Answer: c Explanation: Pressure varies up and down in a cylinder due to suction. Thus it is dependent on the z plane distance of the cylinder.
Answer: c
Explanation: Pressure varies up and down in a cylinder due to suction. Thus it is
dependent on the z plane distance of the cylinder.
See lessCharges filled inside a cylindrical will possess flux in which direction?
Answer: c Explanation: The flux due to the charges will act outside the cylinder. Since the cylinder possesses curved surfaces, it will flow laterally outwards.
Answer: c
Explanation: The flux due to the charges will act outside the cylinder. Since the cylinder
possesses curved surfaces, it will flow laterally outwards.

Answer: b Explanation: r = √(x2+y2+z2 ) = √14 = 3.74 Θ = cos-1 (z/r) = cos-1 (-1/3.74) = 105.5⁰ Φ = tan-1 (y/x) = tan-1 (3/2) = 56.31⁰.
Answer: b
Explanation: r = √(x2+y2+z2
) = √14 = 3.74
Θ = cos-1
(z/r) = cos-1
(-1/3.74) = 105.5⁰
Φ = tan-1
(y/x) = tan-1
(3/2) = 56.31⁰.
