A negatively charged rod is moved near conducting sphere as shown. What will be the movements of the electrons and protons in the conducting sphere?
Electrons | Protons | |
A | move to left | move to right |
B | move to right | move to left |
C | does not move | move to left |
D | move to right | does not move |
Ans 1:
Class : Class 8
B is the correct answer, as the protons might be a part of the nucleus, but the nucleus as a whole is a positively charged particle as well, therefore, it moves to right
Ans 4:
Class : Class 9
Option (D), electrons move from left to right & the protons are stable in the nucleus and they never move.
Ans 7:
Class : Class 10
B is correct answer because,as we know protons are heavy and dont move but due to the movement of electrons protons are pushed towards the opposite direction

chalk powder is insoluble in water while others are soluble, chalk powder can be separated from water by sedimentation and decantation or filtration but others need evaporation...… Now I think Harsh you understood why the answer is D!!

5 is the answer because there is even semi circle there with rectangle,square and triangle.

How are we supposed to know it’s a rectangle when hidden by the circle ,bonne nuit
Ans 4:
Class : Class 6
all listen it should be 5 as i think because the rectangle is dividing the circle into two halves which is forminig a semi circle and if sof has to 4 which means that it should be a whole shape like circle triangle etc.so if it is wholes shape SOF is right or elseNiteen Jit Sahu and all others who say semi circle are right

I'm confused about the same thing...friction opposes relative motion, so it will obviously be towards west??
Ans 6:
Class : Class 8
the answer has to be d because friction always oppose the relative motion of an object no matter if it accelerates or not.
Ans 7:
Class : Class 9
The correct answer is d as friction acts opposite to the direction of the applied force
Ans 8:
Class : Class 8
I think that option "D" is the correct answer as friction is always opposite to direction of motion of the object
Ans 15:
Class : Class 8
How can the direction of friction be towards east? It should always act in the direction opposite to that of the direction of the moving body, i.e., friction should act towards the west irrespective of whether the vehicle is accelerating or retarding. So the correct answer should be D!

see guys, i think u all are mistaken. We dont consider in what direction the car is going, but in which direction the wheel is turning. for the car to go forwards, the wheel must roll clockwise. so for the car to go east, wheel must roll in the clockwise direction. Now consider a very small part of the wheel which is touching the ground. to wheel to roll in clockwise direction , that small part must slide backward, and that must continously happen in order for wheel to turn clockwise and car to go in east direction. And u know, friction is b/w the surface in contact, i.e the rolling part of the wheel, not with the car. so friction should oppose the backward-going part of the wheel, and thus in the ame direction with the motion of the car. if friction were to be in west, the car would never go in east direction, because the wheel would'nt have any force to oppose, to make it go in that direction, and thus the car would never be able to go towards the east direction!
