Answer (4)

4.

Answer (4)

5.

Answer (1)

% = 2% v=3

15. Answer (2)

n2 = 3.6 = 36 × 10–1 7.

Answer (3) [px] = pxr qt 2

8.

0.06 × 100 = 1 % 6

d% = 4%

x = Asin(ABt)

16. Answer (4)

A = [L]

9.

0.005 × 100 = 1 % 0.5

m πr 2 d% = m% + 2r% + %

= F = [MLT ]

Dimension of ABt =

0.003 × 100 = 1 % 0.3

d=

n1u1 = n2u2

6.

S% = 4 = 2 % (s = 6 2)

Maximum % error = 3L% + 2T% [L0T0]

1 = [L−1T −1] [L] [T]

Answer (3)
