1.	Figure shows a weighing-bridge, with a beaker P with water on one pan and a balancing weight R on the other. A solid ball Q is hanging with a thread outside water, It has volume 40 cn^(3) and weighs 80 g. If the solid is lowered to sink fully in water, but not touching the beaker anywhere, the balancing weight R' will be
Answer» same as `R` `40 g` less than `R` `40 g` more than `R` `80 g` more than `R` Solution :Since not touhcing, So `R = F_(B) = rho_(1)(VG) = 40G`. `R' - R = 80G - 40g = 40g` Hence, `R'` will be `40g` more than `R`
