Question

A block of mass 2kg is hanging by attaching it to a long light string whose other end
is hold by a person.
i) If a force of 30N is applied on the string find the tension in the string and the
acceleration of the block.​

Answer 1

$\text\color{orange}{Question : }$

A block of mass 2kg is hanging by attaching it to a long light string whose other end is hold by a person. If a force of 30N is applied on the string find the tension in the string and the acceleration of the block.

$\text\color{orange}{Given : }$

$\text\red{Mass = 2kg ; Force = 30N}$

$\text\color{orange}{Pre-Knowledge :}$

$\text{Force = Mass × acceleration = ma}$

$\text\color{orange}{Solution :}$

$\text{F = ma}$

$\text{30 = 2 × acceleration}$

$\text{ \frac{30}{2} = acceleration}$

$\text\pink{15 m/s² = acceleration}$
