A non-conducting cube of side length 1m has a spherical cavity of radius 0.1m inside it. The system has a charge density of 2.5 C/m3. What is the total flux coming out of the surface of the cube?

Net electric flux through a cube is the sum of fluxes through its six faces. Consider a cube as shown in figure,having sides of length L = 10.0 cm. The electric field is uniform, has a magnitude E = 4.00 × 103NC-1 and isparallel to the xy plane at an angle of 37o measured from the +x -axis towards the +y -axis.(i) Electric flux passing through surface S6 isa) -24 Nm2 C-1 b) 32 Nm2 C-1 c) -32 Nm2 C-1 d) 24 Nm2 C-1(ii) Electric flux passing through surface S1 isa) -32 Nm2 C-1 b) -24 Nm2 C-1 c) 32 Nm2 C-1 d) 24 Nm2 C-1(iii) The surfaces that have zero flux area) S2 and S4 b) S3 and S6 c) S1 and S2 d) S1 and S3(iv) The total net electric flux through all faces of the cube isa) 24 Nm2 C-1 b) 8 Nm2 C-1 c) -8 Nm2 C-1 d) zero30. Read the text carefully and answer the question.A transformer is essentially an a c. device. lt cannot work on d.c. It changes alternating voltages or currents.It does not affect the frequency of a.c. It is based on the phenomenon of mutual induction. A transformeressentially consists of two coils of insulated copper wire having a different number of turns and wound onthe same soft iron core.The number of turns in the primary and secondary coils of an ideal transformer are 2000 and 50 respectively.The primary coil is connected to the main supply of 120 V and secondary coil is connected to a bulb ofresistance 0.6 Ω.1. What will be the value of voltage across the secondary coil'?2. Find the value of the current in the bulb.3. What Will be the value of current in the primary coil'?ORCalculate the power in primary coi

An electric charge q is placed at one of the corner points of a cube of side a. What will bethe net outwards flux coming out of the cube due to the point charge?

An uncharged nonconductive hollow sphere of radius 17 cm surrounds a 14 µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. Calculate the electric flux through the hole. (units of N m2/C)

A point charge causes an electric flux of3 2 12 10 Nm C− to pass through a sphericalGaussian surface of 20.0 cm radius centered on the charge. If the radius of the Gaussiansurface were doubled, how much flux would pass through the surface?
