The force of repulsion, F newtons (N), between twoparticles is inversely proportional to the square ofthe distance, d m, between the particles.(i) Write down a formula connecting F and d.(ii) When the particles are a certain distance apart,the force of repulsion is 20 N. Find the forcewhen the distance is halved. |

Answer» Answer: (i) F=kQ1Q2/d^2 .......(ii) The force of repulsion would be 80N. Step-by-step explanation: As,from FORMULA (i) U can see that F is inversely proportional to d.So by keeping the other parameters constant the new force would be inversly prop. to d^2.Thus,if distance would be HALVED then the force would be DOUBLED but due to square,if the distance would be halved then force would be quadrupled. Hopefully u would have got me. |
