Question
1) A spherical surface completely surrounds a collection ofcharges. Find the electric flux through the surface if thecollection consists of a single +3.93E-6 C charge.2) A plate carries a charge of -2.52C, while a rod carries acharge of +2.19C. How many electrons must be transferred fromthe plate to the rod, so that both objects have the samecharge.
3) Two charges are placed on the x axis. One of the charges (q1 =+8.06 C) is at x1 = +2.79 cm and the other (q2 = -21.8C) is at x1 = +8.94 cm. Calculate the net electric field at x= 0 cm.
4)Two tiny conducting spheres are identical and carry charges of-19.8 C and +49.8 C. They are separated by a distanceof 2.52 cm. What is the magnitude of the force that each sphereexperiences?
Can somebody please help me! i got one try on each left... theyreannoying me, i know im making little mistakes.. if you want me toshow work i will. heres what i did on question 4) keep getting thisanswer -1.395 (which is wrong) and i used F = 8.99E9*Q1*Q2/r²
THANK YOU SOO MUCH TO WHO EVER ANSWERS THIS!!
Explanation / Answer
Be sure your units are correct. Looking at question 4) Q1=-19.8x10-6C; Q2=49.8x10-6 also your distance must be meters not centimeters r=.0252 you should get F=13959N You are using Coulomb's Law so you use the absolute aues ofthe charges to calculate the force F. Magnitude must bepositive.also your distance must be meters not centimeters r=.0252 you should get F=13959N You are using Coulomb's Law so you use the absolute aues ofthe charges to calculate the force F. Magnitude must bepositive.
