Question

The pole of a bell rent in 8cm high and he l lenghth of the slant side in 11m lohat angle does the side make with the ground?​

Answer 1

Answer:

Step-by-step explanation:

Length of the rectangular wire, l=8cm=0.08m

Width of the rectangular wire, b=2cm=0.02m

Hence, area of the rectangular loop,

A=lb

$= 0.008 X0.002\\= 16 X 10 ^{-4} m^{2}$

Magnetic field strength, B=0.3T

Velocity of the loop, v=1cm/s=0.01m/s

(a)

Emf developed in the loop is given as:

e=Blv

$= 0.3 X 0.08X 0.001X =2.4 X 10^{-4} V$

Time taken to travel along the width, t = $\frac{Distance traveled}{Velocity }= \frac{b}{v} \\=\frac{0.002}{0.001}= 2$
