Answer 1

Explanation:

Given Figure shows a small ball of mass m held at rest  by means of two light and inextensible strings.  The tensions in the inclined string at the instant  shown and just after cutting the horizontal string  are respectively

• Now before cutting we have
• Since there is alternate interior angles, theta 1 = theta 2
• Now we have T1 cos theta = mg
•          So T1 = mg / cos theta
• Since the string is similar T1 = T2
• Now after cutting we have
• Since mg sin theta acts in the horizontal direction, we have mg cos theta acting downwards.
• Therefore T1 = mg cos theta.
• So it is considered as mg cos theta always acting with angle theta with mg sin theta.
