At 8:00 how can there be an "upward force"? The weight is downwards and when the 2kg object is released the acceleration for the 3kg object would also be downwards. I'm confused!!

I think upwards force here means the force of 3 kg object being pulled up

On the last question no. 11(a)(i) how did you conclude that the gold nuclei is positively charged?
@rishabhtalwar573 Жыл бұрын
It is because nuclei consists of protons and neutrons. Neutrons have no charge and protons have a positive charge. So the overall charge of a nucleus is positive.

Correction 52:01 it’s 0.83 not 1.2

The correct answer is 1.2 ohms as you need to reciprocal the 5/6 to 6/5 it's a rule for to calc parallel resistance.

wouldn't we use flemings right hand rule in Q7 C?
@tanujaphatak7509 Жыл бұрын
right hand rule is used for motors

@@tanujaphatak7509that's actually the wrong interpretation, if we are passing the current through a magnetic field(as in this paper) , that in itself is the motor effect, and we will use Flemming's left hand rule, however if we are applying a force to a conductor within a magnetic field and yielding out a current then this is the concept of an ac generator and thus we use right hand rule.
