Avneet buys 9 square paving slabs, each with a side of 1/2 m. He lays them in thr form of a square. (b) Shari does not like his arrangement. She gets him to lay them out like a corss. What is the perimeter of her arrangement [(Fig 10.7(ii)]?

Avneet buys 9 square paving slabs, each with a side of 1/2 m. He lays them in thr form of a square. (d) Avneet wonders if there is a way of getting an even greater perimeter. Can you find a way of doing this ? (The paving slabs must meet along complete edges i.e. they cannot be broken.)

Consider a uniform electric field vecE=3xx10^(3)hatiNC^(-1) a. Whate is the flux of this field through a square of 0.1 m on a side whose plane is parallel to the y-z plane? b. What is the flux through the same square if the normal to its plane makes a 60 angle with x-axis?

Let S_(1) , S_(2) ,"……." be square such that for each n gt 1 , the length of a side of S_(n) equals the length of a diagonal of S_(n+1) . If the length of a side of S_(1) is 10cm, then for which of the following values of n is the area of S_(n) less than 1 sq cm ?

Two narrow bores of diameters 3.00mm and 6.0mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3 times 10^-2 N m^-1 .Take the angle of contact to be zero and density to water to be 1.0 times 10^3 kg m^-3
