Two springs, R and S, are used in separate spring-loaded safety catches. Spring R has twice the spring constant of spring S. Both springs are compressed by the same distance, within their limits of proportionality. Which statement is correct?
The force required to compress spring S is twice the force required to compress spring R.
The force required to compress spring R is twice the force required to compress spring S.
The force required to compress spring R is four times the force required to compress spring S.
The force required to compress spring R is the same as the force required to compress spring S.
