Q) If the distance between the points (4, p) and (1, 0) is 5, what is the value of p?

(Q 21 – 30/2/3 – CBSE 2026 Question Paper)

Ans:

Step 1: We know that the distance between the two points (x₁,y₁) and (x₂, y₂) is given by:

Step 2: Here, we have points (4, p) and (1, 0)

∴ = 5

∴ = 5

∴ = 5

∴

∴ 9 + p ² = 25

∴ p ² = 25 -9 = 16

∴ p = √16 = 4

Therefore, the value of p is 5.
