Elastomers are polymers with elastic properties. Neoprene is a type of elastomer formed by polymerizing chloroprene.
It has: High elasticity, Resistance to weathering and ozone.
Applications in wetsuits and industrial belts. Other options like polyvinyl chloride and nylon-6 are not elastomers but thermoplastics or fibers.
Two charges, \( q_1 = +3 \, \mu C \) and \( q_2 = -4 \, \mu C \), are placed 20 cm apart. Calculate the force between the charges.
