W ∝ L2 and W = 6 when L = 4. If L = √17 find W
-
A.
67/8 -
B.
65/8 -
C.
63/8 -
D.
61/8
Correct Answer: Option C
Explanation
W ∝ L2
W = KL2
K = W/L2
K = 6/42
K = 6/16 = 3/8
W = 3/8 L2
W = 3/8(√17)2
W = 3/8 x 17
W = 51/8 = 63/8
W ∝ L2
W = KL2
K = W/L2
K = 6/42
K = 6/16 = 3/8
W = 3/8 L2
W = 3/8(√17)2
W = 3/8 x 17
W = 51/8 = 63/8
