Question

find the torque when the work done to move through an angle 1/4π radian is 3J

Answer 1

Answer:

12

Explanation:

1/4 × x = 3 joule

x = 3 × 4

x = 12 n/m

Answer 2

Given

• θ = ¼ rad
• Work = 3 J

To Find

• Torque

Solution

☯ W = T θ

• W = work done

• T = torque

• θ = angle (in radians)

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

➞ Work done = T θ

➞ T = W/θ

• T = Torque = ?
• W = Work = 3 J
• θ = angle = ¼π

➞ T = 3/(¼π)

➞ Torque = 12 Nm

∴ The Torque of the body is 12 Nm
