It looks like you've uploaded an image of a physics worksheet focused on
graphical vector addition. Since I can't view images directly, I’ll help you solve the problem based on the description and typical format of such worksheets.
Let’s assume the worksheet contains:
- Several vectors drawn on a grid (e.g., labeled
A,
B,
C, etc.), each with magnitude and direction.
- Instructions to perform vector addition graphically using the
head-to-tail method.
- Problems asking to find the resultant vectors for expressions like:
-
R = A + B
-
C = A − B
-
D = A + B + C
- And so on.
---
✔ General Steps for Graphical Vector Addition:
1.
Draw vectors to scale on graph paper.
2. Use the
head-to-tail method:
- Place the tail of the second vector at the head of the first.
- The resultant vector goes from the tail of the first to the head of the last.
3. Measure the
length (magnitude) and
direction (angle) of the resultant using a ruler and protractor.
4. For subtraction (
A − B), add
A + (−B), where
−B is the same magnitude as
B but in the opposite direction.

Example Problem (Typical):
Suppose we have:
- Vector
A: 3 units east
- Vector
B: 4 units north
Then:
#### 1.
R = A + B
- Draw
A → 3 units right.
- From the tip of
A, draw
B → 4 units up.
- Resultant
R is from start of
A to end of
B.
- This forms a right triangle: R = √(3² + 4²) = 5 units.
- Direction: tan⁻¹(4/3) ≈ 53° north of east.
So,
R = 5 units at 53° N of E.

How to Solve Your Worksheet:
Since I can’t see your image, here's how you should proceed:
1.
Identify each vector (A, B, C, etc.) from the diagram.
2.
Note their magnitudes and directions (e.g., 5 units at 30°).
3. For each expression:
- Redraw vectors head-to-tail.
- Draw the resultant.
- Measure length and angle.
4. Write answers in boxed form.

Common Expressions on Such Sheets:
| Expression | Method |
|----------|--------|
|
A + B | Head-to-tail |
|
A − B | A + (−B) |
|
A + B + C | Chain them head-to-tail |
---
Tips:
- Use a ruler and protractor.
- Label all vectors clearly.
- Check if vectors are drawn to scale (e.g., 1 cm = 1 unit).
- Always include both magnitude and direction in your answer.
---
If you can describe the vectors or provide details (e.g., "Vector A is 4 units right, B is 3 units up"), I can walk you through the exact solution step by step.
Alternatively, you can
type out the vectors and problems, and I’ll solve them for you!
