Question

(a)x (dl) Pigure 3:x component of electric filed va -4. Rour charges are located at the corners of a aquare an shown below. Which best dencriben the electrie potential V and electrie Bled E at the center? +2C -2C +2C Figure 4: 5. If an electron moves from 10 V to 5 V, its Kinetic energy will : (say initial KE is 10 J) (a) increase (b) decrease ·6 what will be the electric potential inside a conducting metal sphere of radius R and surface charge density ? (a) (o R)/eo (b) 2o/(Reo )(c) O (d) none of them

Explanation / Answer

4..a) by symmetry of square, it is evident that potential V will be zero. due to different charges net electric field E will non zero.

so a option.

5. kinetic energy will decrease.so b option

6.answer will be option a.
