Answer 1

Answer:

hey here is your answer

Explanation:

as we know that F∝R

so let F/R = K where K is any constant

50/10 = K

5 = K

now the value of K remains same because it is constant.

so

F°/R° = K

100/R° = 5

so we get R° = 20 ohm

so option A is the correct answer

Answer 2

Answer:

As we know frequency is directly proportional to the resistance i.e

f proportional to R

f1/R1 = f2/R2

hence R2 = (f1/R1)*f2

or R2 = 20 ohm

so a.) is right ans.

Hope it'll help you..
