In the equation F = ma, if mass is doubled and acceleration is halved, force becomes
A. Half
B. Double
C. Same
D. Four times
Answer: Option C
Solution (By JKSSB Mock Tests)
F = m×a. New force F' = (2m)×(a/2) = m×a = F. So force remains unchanged. This is direct proportionality. Understand the relationship: doubling mass doubles force, halving acceleration halves it, net effect no change.
