Answer:as we know that terminal velocity is given by
mg/6¶nr
It shows that terminal velocity of the body is directly proportional to the weight Of the object For same radius
The lighter air filter table tennis reahes terminal velocity the first . It's mass is less for the same shape and size so the friction force of upward a resistance becomes equal to the downward force of MG Sooner, In addition to To hit The force of gravity E On the water filled table tennis ball Is larger If terminal velocity is larger And it strikes the ground first
