Q. A small sphere is suspended by string from the ceiling of a car. If the car begins to move with a constant acceleration a, the tension generated in the string is

$m g^{2} + a^{2}$

$m g^{2} - a^{2}$

$m g^{2} + 2 a^{2}$

$M g$

Net acceleration(a)' $= a^{2} + g^{2} + 2 a g cos θ$
$θ = 9 0^{\circ}$
$a^{'} = a^{2} + g^{2}$
$T = m a^{2} + g^{2}$

mg2+a2​

mg2−a2​

mg2+2a2​

Mg

$m g^{2} + a^{2}$

$m g^{2} - a^{2}$

$m g^{2} + 2 a^{2}$

$M g$
