# [J2] Lesson 37 (E-Field Grade A Questions + Complex Numbers Grade A Questions+ Periodic Table 2)

[J2 Physics PMCians] Gravitation (Grade A) Revision

What we did in 2 hours:

This week, we reviewed Grade A questions on Electric Field
We examined the difference in analysing a Potential-distance graph (V-r) vs Electric Field Strength-distance (E-r) graph, and how to solve questions involving Uniform Electric Field.

What you take home:

Electric Field Grade A Test 1 &  Electric Field Grade A Test 4
(for reference only)

Special Mention:

Next lesson, we move on to Grade A questions on EM & EMI.
From all of us at PMC, we wish you good success in your prelims!!
See you all next week.
From you friendly tutors,
Mr Sim & Mr Kwok 🙂

What we did in 2 hours:

Grade-A revision begins with Complex Numbers! As the chapter with arguably the widest difficulty range, the toughest Complex Numbers questions are very daunting. But do recall what we realised in those practices – its very much about trigo, especially the half angle relationships (from double angle formulae).
The Application Question on inductance was an eye-opening look at actual application of Complex Numbers, and you will recall that it was much more manageable than how it was at first glance. Track the constants, read what the question wants you to work towards, and do not panic!

What you take home:

Weekly Quiz: Worked solution for Quiz I is uploaded into the link. There is no new quiz this week, focus on your Prelims!

Special Mention:

Grade-A questions this week moves on to Vectors.
See You and Stay Healthy!

[J2 Chemistry PMCians]

What we did in 2 hours:

We have completed our revision on Periodic Table, arguably the most tiring chapter of the whole syllabus. We have quickly looked at reactions of Period 3 oxides and chlorides, then moved onto Group 2 elements, pay attention to the decomposition of its carbonates, as well as Group 17 elements, focusing on oxidising properties of the halogens and reducing ability of its halides.
The full solutions to the open ended questions are found at the back of the booklet. Do take note of the error in numbering.

What you take home:

The solutions to Consolidation Quiz for Periodic Table, as well as Structured Question 27 is found here:

Special Mention:

Next lesson, we shall boost our knowledge in Atomic Structure and Gaseous State, which will definitely come out for MCQs. Reminder to bring your Secrets Enclosed for both physical and inorganic chem.
Stay safe and healthy!
