Question

a force is applied prependicularly on a door 400 cm wide which required a torque of 1200 Nm to open it . what will be the minimum force required​

Answer 1

Answer:

300 newton

Step-by-step explanation:

torque=force*distance

force= 1200/4 ( distance should be in metres as torque is in Nm)

so force=300 Newton

Answer 2

Answer:

The answer is 300N

Step-by-step explanation:

Torque is 1200

Distance is 400 cm which has to be calculated in metre

It will be 4 m

We know,

Torque = Force * Perpendicular distance

1200 = Force * 4

therefore force will be 300 Newton
