Answer:
B) 2P
Explanation:
Pressure of gas = P
Mass of molecules is halved and speed is doubled, Thus,
P = 1/3 mn / V . V²ᵣₘₛ
When mass is halved and speed is doubled then
Resultant pressure = Pᵗ = P2/P1 = m2/m1×(v2/v1)²
= (m1/2)/2×(2v1/v1)²
= 2 - P2 = 2P1 = 2P0
Thus the resultant pressure will be 2P.
