The edge of an aluminium cube is 10 cm long. One face of the cube isfirmly fixed to a vertical wall. A mass of 100 kg is then attached to the opposite face of the cube. The shear modulus of aluminium is 25 GPa. What is the vertical deflection of this face?

What will be the total flux through the faces of the cube with side of length a if a charge q is placed at mid point of an edge of the cube.

A charge q is placed at the centre of a cube of side l . What is the electric flux passing through two opposite faces of the cube?

A transparent cube of side 210 mm contains a small air bubble. Its apparent distance, when viewed through one face of the cube is 100 mm and when viewed through the opposite face is 40 mm. What is the actual distance of the bubble from the second face and what is the refractive index of the material of the cube?

A charge (q) is enclosed in a cube, what is electric flux associated with one of the faces of the cube?

What is the net flux of the uniform electric field through a cube of side 20 cm oriented so that its faces are parallel to the coordinate planes?

Shows a cube with side of length a. What will the total flux through the faces of the cube, if a charge q is placed at B, mid-point of an edge of the cube?

The side of a cube is 21 cm. A hemisphere whose base diameter is equal to the side of the cube is scooped out from one of the faces. Find the total surface area of the solid so obtained

One face of a glass cube of side 0.06 m is silvered.An object is placed at a distance of 0.07 m from the face opposite to the silvered face.Looking from the object side,the image of the object appears to be 0.11 m behind the silvered face.Calclate the refrative index of the material of glass.
