Answer 1

$\bf \huge \bigstar \underline{Question : }$

80 railway wagons all of same mass 5x10^3 kg are pulled by an engine with a force of 4x10^5N the tension in the coupling between of 30th and 31th wagon from the engine is?

$\bf \huge \bigstar \underline{Answer : }$

Given:

• Mass of each wagon = 5×10³ kg

• Force applied on the engine = 4×10^5 N

Soln:

Total mass of 80 wagons = 80 × 5 × 10³ kg

ma = 4×10^5

a=1 m/s²

So , weagon the right side which produces tension!

⚽ T = 50 × one wagon mass × a

⚽T = 50 × 5 ×10³×1

⚽T = 25 × 10⁴ N

Therefore,

The tension in the coupling between of 30th and 31th wagon from the engine is 25 × 10⁴N!!!

Answer 2

➭ Questíon :-

$\longrightarrow$80 railway wagons all of same mass 5x10³ kg are pulled by an engine with a force of 4x10⁵ N the tension in the coupling between of 30th and 31th wagon from the engine is

➭ Given :-

$\longrightarrow$Mass of each wagon = 5 × 10³kg

$\longrightarrow$Froce applied on the engine = 4 × 10⁵N

➭ To find :-

$\longrightarrow$The tension in the coupling between of 30th and 31th wagon from the engine

➭ Solution :-

→ Total mass of wagons

= 80 × 5 × 10³kg = 4 × 10³kg

$\longrightarrow \boxed{ \bf \: F = ma} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \longrightarrow \rm 4 \times {10}^{5} = ma \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \longrightarrow \rm 4 \times {10}^{5} = 4 \times {10}^{5} \times a \\ \\ \longrightarrow \rm a = \cancel \frac{4 \times {10}^{5} }{4 \times {10}^{5} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \longrightarrow \boxed{ \rm a = 1m {s}^{ - 2} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

so,wagon to the right side wide produces tension

$\longrightarrow \rm T = 50 \times one \: wagon \: mass \times a \\ \longrightarrow \rm T = 50 \times 5 \times {10}^{3} \times 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \longrightarrow \boxed{ \rm \: T = 25 \times {10}^{4} n} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Hence, the tension in the coupling between of 30th and 31th wagon from the engine is 25 × 10⁴N

=======================

➝ MoRe to know....♪♪

• The tension force is the force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.
• The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.
