IGCSE Physics CIE question

IGCSE Physics CIE question

MRWAFFLE

Sorry, I just want clarification for physics. Do we write the answer in 2 significant figures or 3 significant figures.
It mentioned nothing on the question paper AND Ive seen some mark scheme in 2 significant figures. Thanks!
Ps. Paper 4 theory

You should write answers to the number of sig figs in the question. So if you are given a mass of 6.0kg and an acceleration of 2.53m/s² then you answer would be F=15N as 2 sig figs was the smallest used in the formula.
