Question

If a cyclist doubles his speed while negotiating a curve, how does the tendency to overturn vary? 

विकल्प

• Remains unchanged. 

• Doubled.

• Halved.

• Quadrupled

Answer 1

Quadrupled.

Explanation:

The tendency to overturn depends upon centrifugal force, `"mv"^2/"r"` experienced by the cyclist (in this frame of reference)

Ifv is doubled then v² = 4v²

`"mv"^2/"r" = 4 "mv"^2/"r"`

∴ Tendency to overturn is quacbupled.
