SPM Physics:AHA! Root Sign Challenge- Cover It All!

 

One tiny mistake in notation can cost big marks. Many students draw the square root sign too short, leaving the denominator outside. This comic shows the trap:

• Wrong:
  $\sqrt{2GM}\mathrm{/}R$
  → denominator left outside → wrong answer.

• Correct:
  $\sqrt{\frac{2GM}{R}}$
  → whole fraction under root → correct answer.

The lesson is clear: root sign must cover all terms. Neat working and proper notation are as important as the calculation itself.

AHA! Long root, full marks. Not by sight, but by INSIGHT!
