1. A spring balance has a maximum reading of 10N and the length of the calibrated scale is 20cm. A rectangular metal block measuring 10cm by 3cm by 2cm is hung on the balance and stretches the spring by 15cm. Calculate
i) the weight of the block;
ii) the mass of the block;
iii) the density of the metal from which the block is made.(Assume G 10m/s^2)
I'm not sure how to attempt the question, but my friend tried to help me but he doesn't even know himself... I must do this question. :(
