A small mass m starts from rest and slides down the smooth spherical surface of R. Assume zero potential energy at the top. Find the kinetic energy at point where it has traversed through θ angle.mgRcosθmgR(1−cosθ)mgR(1−sinθ)mgR(1+cosθ)

A small mass $m$ starts from rest and slides down the smooth spherical surface of $R$ . Assume zero potential energy at the top. Find the kinetic energy at point where it has traversed through $θ$ angle.

$m g R cos θ$
$m g R (1 - cos θ)$
$m g R (1 - sin θ)$
$m g R (1 + cos θ)$
