Read the following short write-up and answer the questions at the end of it The name ‘silica’ covers an entire group of minerals, which have the general formula 
the most common of which is quartz. Quartz is a framework silicate with 
tetrahedra arranged in spirals. The spirals can turn in a clockwise or anti-clockwise direction 
a feature that results in there being two mirror images, optically active, varieties of quartz The following pictures represent various silicate anions. Their formulae are respectively

In the figure shown all the surfaces are frictionless, and mass of the block, m = 1 kg. The block and wedge are held initially at rest. Now wedge is given a horizontal acceleration of 10 
by applying a force on the wedge, so that the block does not slip on the wedge. Then work done by the normal force in ground frame on the block in 
seconds is:
