Answer 1

$\bold {\huge {Your ~answer :-}}$

$\bf\huge\boxed{12.8 \: N}$

Option incorrect.. Misprinted (1) 12.81 is correct. Kindly contact to ur faculty.

══════════════

EXPLAINATION ➣

Angle made with horizontal

$= cos^{ - 1} ( \frac{25}{4} ) = 51.317$

From force balance

vertical component of tension = mg

⇨ T sinθ = mg

⇒T sin(51.317) = 1 × 10

⇒ T = 10/(0.78114) = 12.8 N

Therefore, The tension acting in the string is 12.8 N

$\huge\boxed{ANSWER:-}$

➡️T = Mg/cos theta

=> Mg(l+R)/[√(l+R)²-R²]

=> 1× 10 × 65 × 10^-2/√[(65)² - (25)²]

=>T = 10.8N

≈ 10N
