Two point charges of +1C each are placed...

Two point charges of +1C each are placed at a separation of 1m from each other . The force between them is used to lift a group of people . How many people can be lifted with the force ? Asssume 100 kg to be the mass of every person. Take `g=10 m//s^2`

Text Solution

AI Generated Solution

To solve the problem step by step, we will use Coulomb's law to find the force between the two point charges and then determine how many people can be lifted with that force. ### Step 1: Calculate the Force Between the Charges According to Coulomb's law, the force \( F \) between two point charges can be calculated using the formula: \[ F = k \frac{Q_1 Q_2}{r^2} \] ...
