Question

Q. The polynomial (x-a), where a > 0 is a factor of g(x) = 4√2x² - √2. Which of these is polynomial whose factor is ( x - 1/a )?

(a) x²+x+6
(b) x²+x-6
(c) x²-5x+4
(d) x²+4x-3​

Answer 1

Answer:

Correct option is

B

(2.0±0.1) Ω

Let R is the equivalent resistance for parallel combination and ΔR is the error(in its measurement respective to the error in the values of resistors)

Hence,

ΔR=0.1

Hence the resistance of the combination is

R=(2.00±0.1)Ω
