This question asks us to identify the very first television soap opera that was broadcast on Doordarshan, India's national public broadcaster. Let's look at the options provided and understand the history of early Indian television serials.
Doordarshan played a pivotal role in shaping television viewing habits in India. Soap operas, known for their long-running storylines focusing on family life and social issues, became incredibly popular. Identifying the first one helps us understand the beginnings of this genre on Indian television.
Hum Log marked a significant milestone in Indian television history. Its realistic portrayal of middle-class Indian life, its relatable characters, and its social commentary made it a massive success and paved the way for future soap operas on Doordarshan and other channels.
Therefore, Hum Log holds the distinction of being the first television soap opera telecast on Doordarshan.
A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
