Need Help!! Physic Problem 13.22 & 13.26

Problem 13.22 (Multistep) In the region shown above there is an electric field due to charged objects not shown in the diagram. A tiny glass ball with a charge of 8 x 10-9 coulomb placed at location A experiences a force of < 7.2 x 10-5-72 x 10-5, o> N, as shown in the diagram. Part 1 Which arrow (a-j) best indicates the direction of the electric field at location A? j zero magnitude Attempts: 0 of 3 used SAVE FOR LATER SUBMIT ANSw

▼ Part 2 What is the electric field at location A? N/C Attempts: 0 of 3 usedSAVE FOR LATER SUBMIT ANSWER ▼ Part 3 What is the magnitude of this electric field? N/C the tolerance is +/-2% Attempts: o of 3 used SAVE FOR LATER SUBMIT ANSWER SUBMIT ANSWER

Part 4 Now the glass ball is moved very far away. A tiny plastic ball, with charge -9 x 10-9 coulombs is placed at location A. Which arrow best indicates the direction of the electric force on the negatively charged plastic ball? Attempts: 0 of 3 used SAVE FOR LATER SUBMIT ANSWER ▼ Part 5 What is the force on the negative plastic ball? > N Attempts: O of 3 used SAVE FOR LATER su SUBMIT ANSWER

▼ Part 6 You discover that the source of the electric field at location A is a negatively charged particle. Which of the blue Xs below best indicates the location of the negatively charged particle that is the source of the field? ×A 4 3 LINK TO TEXT

Problem 13.26 (Multistep) Lithium nucleus affected by an electric field A proton at location A makes an electric field E, at location B. A different proton, placed at location B, experiences a force F1. Fi 1

▼ Part 1 If E 500 N/C, what isF the tolerance is +/-2% Attempts: 0 of 3 used SAVE FOR LATER SUBMIT ANSWER Part2 Now the proton at B is removed and replaced by a lithium nucleus, containing three protons and four neutrons. The proton at location A remains in place. What is the magnitude of the electric force on the lithium nucleus? For Lil- IN the tolerance is +/-290 Attempts: 0 of 3 used SAVE FOR LATERSUB

Part 3 Now the Lithium nucleus is removed, and an electron is placed at location B. The proton at location A remains in place. What is the magnitude of the electric force on the electron? on e-l the tolerance is +/-2% Attempts: O of 3 usedSAVE FOR LATER SUBMIT ANSw Part 4 Which arrow below best indicates the direction of the force on the electron due to the electric field? j zero magnitude
