From a building two balls 𝐴 to 𝐵 are thrown such that 𝐴 is thrown upwards and 𝐵 downwards (both
vertically). If 𝑣𝐴 and 𝑣𝐵 are their respective velocities on reaching the ground, then

Question: From a building two balls 𝐴 to 𝐵 are thrown such that 𝐴 is thrown upwards and 𝐵 downwards (both vertically). If 𝑣𝐴 and 𝑣𝐵 are their respective velocities on reaching the ground, then

(A) v_{B} >v_{A}

(B) v_{B} =v_{A}

(C) v_{A} >v_{B}

(D) Their velocities depends on their masses

Answer: Option (B)

Solution:

From a building two balls 𝐴 to 𝐵 are thrown such that 𝐴 is thrown upwards and 𝐵 downwards (both
vertically). If 𝑣𝐴 and 𝑣𝐵 are their respective velocities on reaching the ground, then
