Answer 1

Answer:

61 ) total reistance given is 16 k ohm . When cut into 4 equal parts then each resistance is 4 k ohm. After applying it in parallel new resistance is 1 k ohm.

So, 1 k ohm = 10 n ohm

    1000 ohm = 10 n ohm

   n = 1000/ 10

   n = 100.

62)  r = 40 cm = 0.4 m

      n = 20

     B = 3 pi * 10^-2

using biot saverts law ,

B = µo n I / 2 pi r

put all the values in the formula,

I = 3 * 10 ^3 A

63) USe formula ----  F = q ( v × B )

charge on proton = 1.6 × 10 ^ -19 C

Hope it helps.
