let density of wood be p and water be q.

abcpg = xbcqg
F = abcpg - (x + Î”x)bcqg = -Î”xbcqg

a = -Î”xbcqgabcp = -Î”xg/ad

T = 2Ï€√dag

THe correct answer is (D)

d is relative density. Ï_s=d*Ï_w
if x is dipped. thn F= (b*C*x) Ï_wg

time period = 2Ï€âˆšm/k where m= (a*b*c) Ï_s
and k = (b*c)Ï_wg

putting the values gives (D0 answer.
