Question

If two balls of same metal weighing $5gm$ and $10gm$ strike with a target with the same velocity. The heat energy so developed is used for raising their temperature alone, then the temperature will be higher

• A. For bigger ball
• B. For smaller ball
• C. Equal for both the balls
• D. None is correct from the above three

Answer 1

Answer: (C)

Equal for both the balls

Specific heat depends on material, in this case metal for both balls is same so specific heat is same.

$\Delta T\propto c$

and Temperature change depend on specific heat only so Rise in temperature would be same for both. Hence Option C is correct.
