Consider a planet whose mass and radius are both twice the mass and radius of Earth. The acceleration due to gravity on the surface of the planet is 'n' times that on Earth. The value of n is:
If North is called North west , West is called South west , South is called South east and so on . A person walks straight from South west to North east and then turns left . Walks straight and again turns left . Now at what direction he is facing ?
