YES/NO

1.6 

One of the free-body diagrams below  shows all forces acting on the ball. … whilst it is moving up the incline …

D is correct. 

ACCEPT C 

error

4.3.3 

• Statement indicated 7 m from A–C.  What the arrow shows does not  change the question.
• Learners were required to use  “Energy principles” to calculate the  kinetic frictional force between B and  C …
  “So energy principles must be used”

No change. (follow the  memo) 

• The statement is clearly  stating that … slides down 7 m from A to C on  an incline plane.
• Learner cannot use  kinetic frictional force to  calculate kinetic frictional  force.

6.5.1 

• The answer is “AWAY” as indicated in  the memo.
• No correction.

Away at the end of the  statement. 
No change. (Follow the  memo.)

No

7.3 and 7.4

No corrections. Sphere L is +2 μC  before contact with sphere M and  became -3 μC after contact with sphere  M. 

No change. (Follow the  memo.)

No

10.3.2 

No corrections. Increase remains. 
The question is not asking anything about  intensity which has to do with more  ejected electrons but the reference is the  threshold.  
At source A – No electrons (f < fo) but at  source B – there are electrons (f > fo).

No change. (Follow the  memo) 
Source A has frequency lower  than the Threshold frequency … so no electrons will be  ejected.(so number is Zero  electrons) 
Source B has frequency higher  than the threshold frequency … So electrons will be  ejected.(so number is greater  than Zero)

No
