force from fuel is 3.2*10^7N. what will be the resultant force and why? marking scheme says 4.8*10^7 Suchal Riaz
what papers is this? i think you are missing the whole question. The resultant force is the sum of all the forces in a system, and you are not showing the whole question

When its not specified in the m.s my teacher gives half the marks for labelling and half for drawing. To be on safe side, I suggest you always write all the labels visible disregarding the marks. In this diagram you can label the testa/seed coat, endosperm/cotyledon, and plumule(unshaded part on the top).
