K.C.S.E Physics Q & A - MODEL 2019PP1QN12

Figure 5 shows two springs C and D of the same length and equal number of turns made from the same wire.

​State with a reason which of the two springs can support a heavier load before attaining the elastic limit.

answer

• C 
• It has a smaller diameter hence a higher spring constant.
