Question

the diameter of the lead ball is 2.1. the density of the lead used is 11.34 is a g g y c cube what is the weight of the ball

Answer 1

Mass = Volume × Density
= 4/3 πR³ × d
= (4/3) × π × (2.1 cm/2)³ × 11.34 g/cm³
= 55 grams

Weight = mg
= 55 × 10^-3 kg × 9.8 m/s²
= 0.54 N

Mass of the ball is 55 grams
Weight of the ball is 0.54 N
